I must admit that the first 5 min of my gameplay I just listened to this BANGER SOUNDTRACK HOLLY S***!
The idea of the game sound really cool and the ship movement is good, I just think it needs a lot of balancing. The first enemies took way to long to kill and later the enemies sometimes spawn inside you. Also if you get a few upgrades I finished a level with half of the time left and had to wait (maby there is a way to skip and I am just missing it). But all of this is nothing what a small patch couldn't fix.
I would also recommand to use a other way to move around, maby it is just me but aiming while moving was really hard because I could not move in one direction and aim at another.
Again the music is a banger and adds much to the gameplay, love it ! :)
