I liked the sun with the "evil" eyes. It's a bit like a jack-o-lantern. And the art in general is cute. I also like how the level gets lighter over time, which gets scary (and I feel like the arrow showing the time isn't moving at a constant speed, I'm guessing that's on purpose, but it's a bit too obvious). But the flashing exclamation point makes me think some people could get seizures from it (and apparently when it involves the colour red, it might be more likely to do so). I couldn't figure out how to get to the moving platform inside the tower in the second level (or third level, if we count the tutorial). Maybe from the platform on the right, but I'm not sure I could get unto that one either (I did get to the lower one on the left, which seems just too low to jump unto the moving one).
The music works well too. The fast music makes you want to hurry (and now I don't remember what it was like in the level I didn't make it through, but it did fit the level). And yeah, the music on the main menu feels like I've heard it before, but I guess I know why that is, and that's okay.
And I like that there's food lying around on the main menu and on the credits screen. It makes them look fun.
