The game is mostly fine, but has some issues. It's a great concept and cool idea, etc., but has some things that make it not as good. So the bugs with verses, where they appear and disappear and when you want to change them they bug, it's not game breaking but could be fixed.
The man's hitbox is weird. When you turn he's in a different position and he can walk into a wall.
Now, in the magic carpet zone, there's a piece of medallion you can't get. When you try to jump on it from wherever, you die right above it as if you hit the ground. Death in the air. No way of getting it. So it makes the game incomplete.
I liked that you can actually read the books and change the verses, but putting verses in any other than intended book mostly seemed useless. Didn't get how to get rapunzel zone medallion. Otherwise, really good game with good idea. After some time, music also feels quite repetitive.
