It's pretty impressive that you made this in 24 hours. It's simple, but you got a lot of good, varied, interaction in despite the time constraint, with a couple different terrain types, more than one hazard, etc. I liked the rain in particular, although I haven't met the lazer demon ant queen yet.
A couple nitpicks: The first time I interacted with an apple I was at full health - but especially without a health bar the lack of interaction was pretty confusing. There's also moment in the first level where you jump down from a platform (where a flag ant was standing) onto the ground, over some hazards that are below the camera view so you don't know they're there until you hit them or get lucky, which I find pretty frustrating.
Overall though, heckin' good game!
