I like the game.
The game is too easy and too hard at the same time.
The music: it's a very short loop and it get's boring.
The weapons: some weapons are amazing and powerful (rocket-launcher,the "zap" thing) but some are useless (rifles).
The obstacles: sometimes it get's too hard to reach them.
Health (warrior): You can't die easily.
Health (wall): the wall is easy to destroy, which makes the game even harder.
Loading weapons: weapon loading is very long,sometimes it's better to get hit by an obstacle than to let it hit the wall when your weapon is loading.
The speed-up boxes: speed-up is always necessary.
