This game was pretty interesting. The art and writing was super well done! The gameplay was fun, too, if a little rough around the edges. I felt like I went so fast the only practical way to play was to hold down the space bar and just shoot. Perhaps lowering the speed generally or lowering the threshold to which you can ram enemies would make it a bit more practical.I also encountered a bug in level 2 where I clipped out of the level and had to quit out. Overall, though, this game was neat and I had a fun time! Always love to see other folks using pygame as well!
