Not bad at all. I would prefer a relative ship controll (W goes forward) instead of an absolute one (W goes up). Level1 is a bit boring but with the first boss, more enemies on lvl2 and the possibilty to upgrade... it's almost a real game! ;) I couldn't leave the shop though... Thumbs up for more of space-warrior!
I am very pleased to hear that, thank you !! :)
