>You can actually go in and out of Limbo as much as you want without losing any stars. You only lose them if you exit limbo at a different angle that you came in at.
- Not true, you lose stars if you go into limbo over the amount of times that it says you can on the regular levels. However the time modes you can enter limbo as many times as you would like. Personally I think the number on the bottom and the background change work fine. The game is reasonably fun but gets boring after a while - Maybe if you could kill the monsters (apart from dropping them on spikes) it would be a tad more entertaining. Overall I liked it.
