Bomb the Bugs

Climb ladders and drop bombs on bugs for as long as you can without dying. Try to beat your high score. Controls:

Arrow keys = move left, right, and climb ladders.

Space = jump

z = drop bombs

Careful! Bombs can force you to jump!

This is a prototype based on some ideas I've been playing around with. There is no sound, and there are probably technical bugs present. My highest score is 900, what's yours?
