This really was a great game, although it did get frustrating! For some reason, it took a long time to get used to the controls. I guess I'm just not used to these kinds. Anyway, I still managed to put up a good fight. The best part was getting more power from killing enemies. It was hard to get past those walls.
Protip: Slide while jumping to get a longer jump. Being a demon fighting demons is quite fun. I appreciate how there's so much going on. I'm glad there were checkpoints. I wish there was an option to make the game go into fullscreen.
