This game had really nice art and music. The background art is so good! I If you guys continue work on it, I just have a few small criticisms.
One is that I think that if you have a slow move speed, you have to be generous with the checkpoints.
The other is that those enemy rooms are difficult and I pretty much only beat them by "cheating" and getting on a platform and shooting them where they couldn't reach me. Otherwise I would get swarmed and stuck, and was stuck until I died.
But overall great! Good work on this submission guys.
