- There are Cool mechanics you added, they actually surprised me and the game was a lot more then I expected.
- The art changes as you go up, which helps keep things interesting things to look at.
- There is also surprisingly good pacing. I thought that I saw all the mechanics, but a new one would be introduced a few rooms later. It keeps the game fresh even as you go up and kept me playing for a lot longer then I expected. (I don't like rage games usually)
