I like the idea of the game. The moving and shooting in the same direction was a bit confusing to get right(didn't really manage to figure it out). I have to give you credit for all those upgrade options though, there's a nice variety. there is a few areas that could use some improvement such as the controls and the information about the upgrades, it would have been nice to display the description of the upgrades while in the upgrade menu. overall, its a neat little game and I like the simplistic artstyle. my high score was 158
