I noticed the Umi-bozu unfair hand damage during test playing other bugfixes and fixed that already. 👍
I'll see what I can do with the collision issues (the current version of Game Maker has a completely different collision engine so maybe it'll be fixed because of that). The floaties are only ever approached from the top so for them I could probably cheat and make them a lot taller than they are visually so it's not possible to clip through them. I've not observed the issues with falling through 2x2 blocks myself so I gotta look into that... maybe the sword is the answer, since it could affect your hitbox (melee animations use a different sprite from everything else and while they SHOULDN'T affect collision masks, "shouldn't" and "won't" aren't the same thing...)
Coloring the chains yellow gold would be possible, I don't think they're used anywhere else where it could clash.
Enemy projectiles being destroyed offscreen is a feature so I don't wanna fix it even if it IS a cheese, generally if something is unfair in the player's favor it's OK as long (as it doesn't trivialize the game)
Still not sure about the best way to handle ice blocks, it's gonna be frustrating for the player if it's too easy to destroy them accidentally when a puzzle requires you to freeze an enemy to use as a platform.
