It is currently possible to get stuck on Level 25, so if this happens to you, here's how to fix it!
If when standing on the Pink Gem House you spin the block highlighted on the left, you can later get locked in place.
You'll have to reset the whole level (not the Reset button in the menu). You can do this by returning to the Level select and choosing Level 25 again. It'll ask to reset and you say yes.
We're sorry for the inconvenience, but we're working to get a fixed build out!
