Nice one... This whole series is very unique and I like this stylistic art. The games are very simplistic, but intentionally so. I guess 'neko' is Japanese for cat?
Original idea, and a good implementation of it. I would like the option for directional or relative control (a la Frag Assault) since I prefer relative controls myself. Nice sound, and atmosphere.
The part that makes it repetitive is when the enemies recycle in exactly the same place. It shows the limitation of the game engine, but to be fair Eggy only made it in a few hours ^^
