Very nice game! Really love the concept and idea and the variety of "bugs" you can get is nice. Movement and shooting feels nice too, not too slow or fast. The game looks and sounds really good too, it all fits together really well.
The only thing I think could be improved is that it's maybe a bit too chaotic with too many insects to shoot, making it hard to shoot the red ones but not the green ones.
Very nice game overall :) Great job!
