I really liked this game! The funniest thing is that I didn't even know how to properly play it at first, but I definitley got the hang of it later. The sounds in this game are really cool, especially with how the ghosts make this scary sound when they disappear. I appreciate the inclusion of all these great visuals. I also love how you summon new demons when you get a new power. It's just a very well done game.
My biggest suggestion is that you draw a few lines and set everyone on fire all at once. You really don't have to worry about your power replenshing. I had trouble with that at first, but I quickly got a lot better. I don't even know how I did that, it just got better for me. I also like how it automatically pauses for you when you scroll down to review.
