A nice attempt
The idea is cute, and using a laser as an attack is funny, the controls are simple and fine, the enemies are all right, but just one enemy touchey you and it's over, well it's not a good thing if you are against bosses, they can easily end your run, and that's annoying, also the concept is not really a long living type. maybe stages could have been divided into small separate parts with a moving background and allowing your bug to move to avoid attacks just like a shoot em up, so for these things I keep 4 ponts and give a six of ten, way to go, keep on.
