this was a nice entry! the art is great too, the little nerdy character, the title screen with the green rim lighting, it's well done. :) the concept of flinging slower, frictionless discs as your defense is a good one to explore.
i must echo the sentiments of others and say i wish there was more feedback when the bugs get zapped. :( they take many hits and it isn't communicated well enough in the game's current state, which can be frustrating sometimes. but overall, this was great. :)
