Been a while, but I finally did some more work on the game. I fixed some bugs and began working on the upgrade system (I just have concept art for now, sorry about that.) I also implemented a new enemy, the Police Car. This guy can seriously mess up your runs by adding a new obstacle in the form of a vertical dash attack from either the top or bottom of the screen.
He might be a boss at some point. Let me know whether he should be a boss or a normal enemy.
