Very interesting and unique idea! Are you planning to keep working on it post-jam? (I would love to see the game expanded).
Just one thing: I didn't notice there's jump until I've seen it mentioned in the comments. I think it's the way it's written, I must've skimmed over "/ space" part, and just read it as "Controls: WASD. "E" to die". So I thought you can only move left and right and was trying to fill the whole pit with dead bugs. (Not having jump also made sense with "out of control" as well). Maybe you could rephrase the description of controls to something like "Move: WASD. Jump: Space. Die: E" so it explicitly mentions jumping?
