up to rootmars2
First attempt at doing the last part before rootmars 2. 9158 frames saved in total. The first two doors are best destroyed with 2 bombs and 2 shotguns (it's annoying how everything has 240 hp so a single S shot can't take them out). So I'm forced to use S+knife for taking care of some of the zombies.
At the part where I get the 2nd F, if you delay scrolling the screen and kill the extra clone, you can get extra bombs. This ended up only costing about 15 frames, so it's totally worth getting.
At the 3rd door, if you lure a clone near it and throw the slug noid close enough to the door while overlapping the clone, you can destroy all three bubbles(?) of the door. When I didn't get the extra bombs, the clone spawned and came to the door at the right time, but when I did get the bombs, the clone comes too late for this trick to be useful. Maybe this is because the timings were thrown off when I delayed the screen scrolling to get the extra bombs. Changing the time of when I killed the previous clones didn't affect how soon they spawned. So I decided to use a single cannon and 2 bombs to destroy the top bubble and then just threw it at the earliest frame possible to destroy the bottom two bubbles.
I tried my best to make the hoop shooting bots optimized. F is really not suited to fighting them, but I don't think using only bombs is correct. Using the rebel slug cannons for the first two bots ended up only being about 10 frames slower, but saved me some bombs so I decided to use it.
At the end, I tried testing using F+knife on rootmars2. The one in the WIP is the best version I've been able to find. I can't seem to hold down all the time, the player will not use the knife when I try to keep holding down. The input I use for knife is: |↓A|null|←|→| repeat
Faster F glitch?
I found a glitch that allows you to fire F faster. (The glitch occurs at the beginning of the mothership part where you get 2 F). If you get a new F right after you finish using up all of another F, you can fire 2 shots of F within a few frames. It seems that if all you do is fire F, then you can fire the second shot just 2 frames after the first shot. For some reason, if you crouch, throw a bomb, or try to use turn around cancel, the rate you can fire F becomes slightly slower (have to wait about 4~6 frames), but it goes back to being just 2 frames after some time. This does not work when you try to go from big F to normal F (tested this in the last part before rootmars2). I think this will be really useful for rootmars2 and might even make it better to get F instead of G from the redballs.
