Crusader of Centy is an old Zelda knock-off that replaces useful items with useful animal companions. You can have only two animals out at a time, and some will combine their abilities for unique effects. Despite being an action-RPG, very little killing of monsters is actually required other than bosses. Most of the gameplay is centered around swinging and throwing your magical boomerang sword to solve puzzles. This run contains gratuitous use of abusing slide physics, abusing wall collision, abusing monster collision, abusing the bosses, and literally skipping through many of the game's challenges.

This is my first TAS and it's quite a doozy. I started almost a year ago but gave up in a few weeks, only to start over from scratch about a month and a half ago. Previously I'd been using my keyboard to record the run, which was painful to say the least. Using a wired 360 controller was much better, allowing me to hit all four buttons at once and mapping out frame advance, pause, and two sets of save/load commands.

Techniques

Early zoning: You can change zones a few frames early by approaching the screen border or doorway and then stepping back.

Damage boosting: Touching a monster repels you precisely at the angle you approached it from, so it's very easy to line up where you want to go. The speed boost is reflected in what I call "Slide" speed, which adds with your controller momentum (the direction you push) to give your total speed.

Swing interruption: Pressing and holding A usually swings your sword and begins charging. Some things can interrupt your swing and allow you to begin charging immediately, such as a monster, a slide, or a spring. This is useful because while swinging, you lose control of your momentum and slow down.

Jump charging: You retain control of your character if you swing while in the air. Jumping is therefore used often to begin a sword charge. Completely replaces swing interruption after Dahlia Valley.

Slide boost: Your Slide values increase every frame you are on a slippery slope, like a cliff or waterfall. By maximizing the time I spend on a slide, I can build up a lot of momentum and make previously impossible jumps, especially ones the developers didn't think of, and to cross distances quickly.

Rope hop: Some ropes will prevent you from jumping onto them, but the game is very wishy-washy about enforcing it.

Block stop: You are given 3 frames to move before you push a block. If you hide yourself against an obstacle, the game cannot move you.

Wall-hack: When there is an obstacle next to a diagonal wall, you can squeeze in between the two to pass through, or press into it to force the game into resolving that collision, resulting in you being pushed into the wall. If you end up fully in the wall, you are allowed to walk freely around so long as you stay away from legal squares.

Jump swing: With Flash equipped, you move faster than your thrown sword. To clear breakable obstacles without slowing down, jump and swing 16 frames before you land, and your sword will be active for that single frame.

C strafe: While holding C, your angle is locked in. You cannot hold a sword charge while strafing, but it is useful for talking to NPCs and manipulating Rio's position.

Post-menu input: Press any buttons you like while holding Start to exit the menu, and it will be inputted as the screen loads. This allows for sword-charging one frame sooner, quicker movement, and jumping off Rio when he no longer exists.

Stage comments

Rafflesia

If you go through all three courses in this area, the King gives you a Holy Sword, which does double damage. This is a long and tedious affair, and boss fights take an average 15 seconds to begin with. Instead of going through the beginner course, I collect 20 Malins, learn the sword throw, and leave.

Dahlia Valley

Here I demonstrate damage boosting off of monsters, and swing interruption on the spring and waterfall. Dahlia's boss, the Wolf, attacks you with the stars and planets he sees when he hits himself with a 1 ton hammer...the stars allow me to swing interrupt and kill the Wolf quickly, but on the final hit I damage boost into the door before he gives his death speech. By reaching the door early, I completely skip a 20-second dialogue with a grateful Granny.

Anemone Beach

The third screen typically requires >90 seconds of running back and forth hitting switches, but a quicker way is to slide boost off the cliffs and skip over the water.

Hot Daisy

You're supposed to equip Chilly here and freeze that lava pond that I instead slide boost across.

Burn Daisy

The block pushing in screen 1 sets up the wall-hack that allows me to use the last staircase first. Goodbye, level. I collect the money bag here because you need 20 Malins for Flash and 50 Malins for Past Iris. The Shuffler fight is easily the longest wait in the game, so I try to make the most of it with Red Light, Green Light, sword tricks, and other shenanigans.

Iris

This is a long segment. The second wall-hack goes into the cliffside, then up into the trees. The go-kart race against Flash held me up for days as I tried to figure out the physics behind it. As a slime you have instant acceleration, so I use that and the respective waiting times to give the screen a nice shake or two. The last jump in this area was tricky to set up, as it goes onto a switch, then off of another one instantly.

Camellia Desert

Some block-stopping here, slide-boosting with the quicksand pits, and some funny bouncing around with breakable obstacles. Second money bag collected on the second screen.

Tower of Babel

Roxie has several attacks, only one of which leaves him vulnerable. If my luck were better, I could have killed him in two phases.

Castle Freesia

The entire floor is slippery here. Jumping gives you control back while adding your current Slide speed, so you can travel at ludicrous speeds if you build it up enough. Towards the end there is a jump across a pond with a breakable boulder across it; this was one of the hardest jumps in the run to set up. It is possible to exit the Georama fight early and go straight to Babel with the seeds, but it takes a while to go back through Freesia, and Leviathan is very useful.

Root Temple

With judicious use of slide-boosting, I made a mockery of this level's twistiness. Some care was given not to get hit by a bubble. It is also possible here to exit to the world map, but since the temple hasn't been raised, the path going past Castle Freesia is blocked off by a glitch. The Leviathan fight requires you to knock his fireballs back at him, but throwing the sword at him while they appear works better.

Tower of Babel

Abusing the rubber bands was fun and useful. Unfortunately there is a LOT of block pushing here.

Place of Peace

Instead of going through a long, tedious set of switch puzzles, I hitch a ride on a single bumblebee and steer him by moving a few pixels left, right, up and down. I didn't have this idea until I reached the level, but I'm proud of the trick. Maldra was completely emasculated because he didn't know how to turn around...his parts didn't even have time to hit the ground.

Past Iris

I collected the last money bag quickly and re-entered the cliff without hesitation. Once I reached Past Iris, I knew I could easily jump across the water without getting Rio, but I also knew I needed Rio for several puzzles later. He turned out to be a huge asset to me in his chasm-crossing abilities.

Past Camellia Desert

You'll see some C strafing here as I make use of Rio. Chameleon was tricky; the fight went well, but a few frames had to be sacrificed because of his quick shuffling around and grabby tongue in the second phase.

Past Anemone Beach

The Moa+Leviathan switch/throw was difficult to set up, but it looks impressive now. Baron was slightly difficult to deal with, and I couldn't manipulate the fireballs to hit both purple blobs at once.

Past Dahlia Valley

Wall-hacking in full force! I wish I could follow the wall all the way north and transfer to the horizontal wall, but it is impossible without trapping myself on the upper shelf.

Black Night

The very first jump in this segment was hands down the hardest, yet most rewarding. I had to time Rio tracking me and invent a new glitch that involved jumping out of the menu. There was literally no room for error except for four frames that I could manage using diagonally. Although the very next part could be done quicker with Flash+Leviathan, the 122 frames necessary to switch again is just not worth it.

The boss fights were very interesting. In Smell Sense, tiles crack when you walk over them, and turn to spikes when you jump on a cracked tile; after a few seconds, the spikes begin to disappear, but quicker than the appearing spikes. If you make a long enough trail that the disappearing spikes catch up to the appearing ones, the spikes that remain stay there permanently. Unfortunately, when I trapped the boss on a permanent bed of spikes, he remained invincible half the time and it took far longer to kill. Touch Sense was so-so; half the time the fireballs were not co-operating, but I killed them both just in time, so the white-out happened early.
