This is a really neat game. The aesthetics are top notch, I love the goofy enemies that are cute enough to be fun to look at but not too cute to feel bad about killing. Heavily limiting what squares one can paint at any given time leads to excellent strategy, setting up squares several moves in advance while avoiding the erasure of traps already set. The slug-like blobs are a key addition to keep the pressure on, if they weren't there to erase paint the game would become rapidly too easy. Speaking of difficulty, while I did feel pressure as some enemies came within striking distance, I made it about 50 rounds without ever taking damage before I quit, although erring on the side of ease is probably best for a game jam entry. If you wanted to expand this at all, having some sort of roguelike pick-from-3 upgrade system seems fun to work with, or maybe some bosses to deal with. A superb entry, huge props to you. Shlorptastic.
