Really cool puzzle game, the mechanics were very intuitive. I like how the second game mode enabled through cheats increases the difficulty, though not consistently as some were quite easy and others I still haven't figured out yet. (though I plan on coming back to beat them) I also really like the skittering noise the player character makes when moving.
The music toggle doesn't seem to work in the menu. It works in a level just fine but doesn't in the menu for whatever reason. Also, the cat cheat code continues to show the hungry things as cats in the menu when you turn it off, once again it's only in the menu, and returning to the menu from a level after turning it off returns the hungry things to their normal appearance.
