At first I really liked this world. The author spent time on graphics and as a result that world had a nice feel to it. Then however, the level managed to hit both of my “Mario” pet peeves which led of course to the row rating. They are:

1) One of the levels is pure darkness, you can't see the block or the pits. This causes the level to be far more luck than skill.

2) It is possible to stuck in a place where you can't kill yourself but you can't get out either. As a result you have to quick the game completely and start over. This is especially frustrating on the dark level where you can't see ahead of time that you might get stuck, I ended up having to quit and restart 3 times because of this problem.
