Hi! Dev here.
I was browsing my analytics, and found that my highest visits this month are from a website I had never heard of. and I thought "how curious". Nice to meet you all.
To fill in some gaps:
I was having trouble getting the switching lighting between areas on the screen to register, so at the last minute I was forced to lower the hitbox of the acid to match that of the rocket boots.
SKRAAGHRHSCH has 10 hit points, but I don't think that matters too much for you.
Yes the "one screen" is a little bit of a lie, as there are in fact 10 scenes. Your character's items and such stay with you, but there is no hitbox in the boss room to test for acid.

I have a unique scene to show the player moving upwards. In this "RocketShoes" scene, all collisions except for getting up to the top and most of the player input is turned off, and then the scene switches to the "FinalBoss" scene. This is likely why the first B press gets eaten, because you are not in the final boss scene yet.
I am honored that my game has been the subject of such activities, and I am curious about where you found it, and what makes a game a good candidate for TAS? I suppose it is easier to do GBC ROMs because you could play them in something that manipulates time, etc, where as a browser-based game is a little tougher, or a game with a truly random generated world may be difficult to maintain consistency between runs. (for instance,

I would recommend another game of mine that was actually designed as a speed-run :
