Man this is cool! Considering how amazingly well done every other part of this entry is, I think the gameplay could be a little tighter.
Feels like the bombs should probably block you and enemies walking past, and they should get placed on the grid so you know exactly where they're going to go and how far the blast will reach. Falling of platforms and ladders also somehow feels wrong, like you're able to slide around horizontally in a way that you wouldn't have in something like donkey kong.
Honestly this is a few tweaks away from being perfect, Great work!
