Route comments

• 2 player mode could be more interesting, allow more RNG manipulation and maybe improve turn based battles, but would be much harder to optimize, and it doubles the required kill counts in action battles. This can also be switched at any town's convenience store, but would obviously waste time
• The difficulty setting affects enemies' speed in action battles (Easy is slow, Hard is fast) and your starting attack power (1 on Hard, 4 otherwise, then +1 per level). I chose Hard for the faster action, and the reduced attack power doesn't make too much of a difference.

• RNG (at $0130-0132) advances once per frame and per call, so it's generally manipulated by delaying calls or adding some
• Encounters are determined at each tile change (movement is per pixel) and can be manipulated by waiting or turning at specific pixels between tiles, but each direction change costs 1 frame. Several areas have 15-20% encounter rate per tile, so they normally happen quite often

• Punches do [attack+weapon] damage, kicks/jumps/sword do [attack] damage, so currently 13 and 1 (then both +1 per level up), and each enemy here has around 150-200 HP
• Punching blocks has a few possible random effects:
  • Usually nothing
  • "?" ball that will either give one [M] (max 6) or lose them all, in a fixed sequence (approximately every 5th ball is bad, that's the ones I don't pick up). 6 [M] can then be spent on a "Mighty Ball"
  • Block is destroyed and respawns a bit later
  • Block is sent flying in a straight line, killing any enemy it hits (if vulnerable to it, which the ones here aren't)
• Some other battles (not here) have specific spots to punch for chests containing items or bonuses (not random), which will be useful too

• After each hit, they're invulnerable for 120 frames, so it's all about hitting once as early as possible and using only punches (unless one jump doesn't take an extra hit). They can't be hit while attacking or jumping, so I also have to make sure they don't do it at a bad time.
• After every 3 hits, they stay knocked down for 2 seconds. I first use this spare time to pick up 6 [M] for later
• Obviously I avoid getting hit since it wouldn't save time, and anything here would kill me in one hit
• Destroying blocks delays a framerule slightly, that (if not properly aligned) can lose up to 15 frames after entering the door, so I've had to do that a few times
• On the last battle, I repeatedly punch a block to advance RNG for the next part coming

• Punch/Kick damage works the same way as before, and Dragon Kick (unavailable for now, costs 1 [K]) does [attack*2] damage
• Punch has a longer animation, so sometimes a weaker Kick is still worth using
• Call lets Ryu join in 1 player mode, and he'll select Punch/Kick randomly (or Dragon Kick if used) for a second attack per turn. Here it just barely saved more time than it cost to use
• I start by using a Boo Bomb to stun the enemy, which blocks the enemy's attacks, gives me 100% hit chance (instead of 30%), and avoids having to buy the Fire Shield for a 5% dodge chance (and wait several seconds per turn to manipulate multiple 30% and a 5% at once)
• I then use the Mighty Ball for triple damage, and only have to manipulate Ryu's action and stun+mighty lasting forever, making the fight look extremely simple
• 5 punches were just enough (270 HP, 54 per hit), not doing the 2 random encounters would require one more hit here

• Each battle requires 8 kills (or 16 in 2 player mode) to open the door, which also has to be entered as fast as possible. The enemy sequence is fixed, but with random spawn locations (at regular intervals, up to 3 enemies on screen). Enemies don't become vulnerable until they move enough off the edge, and tend to stay there (and attack) if you're near them. This is where the real action begins, and the hardest part to optimize!
• Battle 1: the jumping slugs can't be hit by punches, and the pigs survive one jump, I get 5 [K] (for long jumps or Dragon Kick) from a chest
• Battle 2: ninjas spawn from random blocks and are vulnerable for a very short time before they jump out. I get another Boo Bomb on the way, and the shuriken powerup in a chest gives a ranged attack (with [attack] damage) but only for the rest of this battle
• Battle 3: edge invulnerability is more apparent here and I had to wait a few times
• Boss: the projectile throw causes significant lag and had to be dodged with jumps, and I refill the 6 [M] here while waiting between hits

• Battle 1: all enemies here would survive one jump, and there's no diagonal jump movement on the screen edge
• Battle 2: the block throw kill is seen here, the jumping frog requires a sword
• Battle 3: the dragons have 60 HP and require a sword, so they're not worth killing (and get in the way a lot). I also pick up more [K] and a [*] (T-Star) here, for later
• Battle 4: the bulls can't be hit by jumps, but go down very fast anyway
• Boss: turn based, same strategy as before but now faster without Call, using 3 punches and a Dragon Kick

• Battle 1, 2: now enemies have enough HP to require 2 punches, and some have ranged attacks
• Battle 3: I get a few [M] here while attacking, until the projectile spawns fill all slots
• Battle 4: one enemy + 3 fakes randomly warp around and would take 5 hits, but some manipulation and a block throw make this one very short
• Battle 5: enemies bounce back fast from punches, I get the remaining [M] here
• Battle 6: enemies can't be hit while moving, constantly throw projectiles to dodge, can't be grouped fast enough to be hit together, and have 150 HP (at 20 per punch and 8 per jump now), so this is definitely the worst one to optimize. I considered using a Mighty Ball here (spawns on the edge at a random spot, makes you invincible, then walk into enemies to kill them) but would then immediately need another 6 [M] for the next battle, while avoiding Ryu coming for the combined attack, so I went without.
• Boss: turn based, same strategy again, 4 punches

• The Prism claw is available here by doing a minigame, but wouldn't do any good at this point (2 more punch damage), so it's skipped
• Unlike all other towns, this one can't be warped back to. The menu entry does exist but never gets set, and entering the underground section sets Chatzy instead
• I buy the Fixer here (800 sen), which works like Boo Bomb but uses 1 [*], only because this was slightly faster than getting one more Boo Bomb from random encounters. It's also buyable in Chatzy (1000) but too expensive at that time
• Bell #7 in the palace requires all other bells. I first thought I could clear Yokan during the next trip to save a warp, got here and ... well, had to redo everything, then later realized the best time to buy whirly birds was at the beginning (not while visiting Shorin or Chatzy) and had to redo everything again

• Fixer is used instead of Boo Bomb, but same effect
• The boss has 512 HP, and now (with Mighty Ball active) Punch does 66, Kick 30, Dragon Kick 60
• I used 1 kick, 2 punches, 6 dragon kicks, which was slightly faster than using mostly punches for 1 less hit

Known/possible improvements

• It turns out Tub-A-Tummy can be killed in one hit with a flying block, unlike other bosses or stronger enemies (I only found out after finishing), but it would require getting 6 [M] elsewhere (in any of 7 battles, have fun routing it). This also gives the possibility of clearing Deli-Chous first, with only a few slow kills and a small backtrack (then save one warp and a few hits on Shorin's scholars), but not sure that would be faster
• All of the (non boss) action battles could probably be improved more with a lot of experimentation or different RNG, but I already went through them multiple times (and of course, any change will give different RNG for the rest of the run)
• I had enough [K] left over that could have been skipped or used more, but it was a minimal cost or potential time save
