Controls suck. No one does asteroids controls in shmups anymore for a reason. Making your shots influence movement was an even worse idea.
Upgrades only occurring when you beat your high score means that the better you do the worse off you are.
No explanation as to where ally forces are coming from. They can't be other fighters because I was separated from the fleet according to the game description. Only until first upgrade you find out they're drones.
No clear goal to advance to. Existing plot and gameplay not enough to carry player to vague goal of "see what happens."
Damage system not clear. Smoking and beeping are not an acceptable substitute for a health bar, especially in a game in which how much health you have left is a deciding factor in how to approach an encounter.
tl;dr there isn't enough here to be fun.
