It's a really fun and colorful game. Part of the difficulty arises when there's a bunch of same colored sprites and splashes on the walls. Maybe if there were no enemies with the sprite that looks exactly like yours it would be easier to track your character. But that depends on whether on to you want that.
I started playing your game because it's titled Hammer Time just like ours (https://chairishgames.itch.io/hammer-time) and I was hoping the Hammer would play a bigger role in the game. Maybe it's better that it didn't because color changing in such a hectic enviroment makes for a fun game. Good work :)
