It is a really cool game. I liked it a lot apart from few problems. Well the movement feels a little jank sometimes but that is not such a big deal. The really close camera when outside feels a little too much mainly when moving super fast with upgrades, although I found out that by getting close to the space ship the camera zooms out even outside. Also I don't know if it was intended and I just missed it but when moving the laser weapon around the ship it removed its cooldown killing all enemies basically instantly. Also in the description it says that every 1:30 - 2:00 enemy storm approaches but after playing for a while I am sure that every wave was about 40 seconds.
