okay, at least you were honest about your game ;) But... the gun doesn't work as gun, it kills only on close range (even when you fire from the alien away), you don't receive damage, no rising difficulty, no mute button. Maybe it's okay for class, but not for a game. Try it again and maybe you'll get better
It doesn't make sense, that I loose all upgrades after clearing a level, but the amount of lives stays the same. And enemies can hide offscreen for some reason...
some suggestions:
1. Health- and Throttlebar
2. Pause and Checkpoints
3. not every keyboard setting has x and z at the same place (qwertz vs qwerty for example)
4. Sometimes several people just wait for one person in Multiplayer, but he won't press "ready", so how about a forced kick out after some minutes of inactivity without pressing ready?
