Enjoyed the game, visually simple but small visual fx like the level switcher are a nice touch. There is solid ideas with the projectiles of the different books and progression from each room. The sound fx and music did it justice but would have enjoyed if the music got more intense as the levels got harder and harder. There also were a couple flaws in the game, the black book bomb projectiles that would launch over to you didn't seem to stack correctly you could soak a lot of the damage when it came to the later levels. Also there is nothing really stopping you from staying in the first level for a long time stacking up coins past 100+ and then just rushing past the next couple levels getting to the higher levels really quickly. Overall though fun game I could see some minor balancing tweaks making this very hard and competitive to score against friends seeing who can get to the highest floor :)
