I didn't care for that much.

Sweet! Black Shell does Bullet Hell! :D

Someone put an effort to actually construct this game, I give them credit for that, however, it is basically unplayable.

There is no real direction as to what you are supposed to do or where you are supposed to go. A lot of the transitions from scene to scene are off and the collision detection of objects seems to be off as well.
Also, the sprites are all from different packs, which kind of kills any sort of immersion.

However, this is 'playable' and there was some effort put into it.

This is a really good 'asteroids' kind of game. Nice sharp graphics, and varying enemy types as well as power-ups offer a lot more strategy than others in the genre! Thumbs up.
