Time Challenge Mode: If you finish a puzzle in Inventor Mode, it will be unlocked here. This time, it will take fewer moves to reach a solution, but you only have 30 seconds to find it.

Move Challenge Mode: Take your time and plan ahead. Every click counts when you only get ten moves to find a solution.

Beautiful and fun

I love the visuals. I tore through this lite version in about 15 minutes and I may buy the full version. For an adult these puzzles are pretty easy (so far), so I may but this would be great for my kids. Developers: your 3D objects rotation (on levels where you can rotate the entire puzzle by shift-dragging) suffers from gimble lock... check out Quaternions to provide a better roller-ball motion.

Worth a look

Beautiful graphics and easy controls. More levels, especially in the free version would be nice. Definitly seems worth spending some money to support and play more advanced levels.

Fun game, beautiful graphics

Note: v1.1.0 works great on Yosemite. If you haven’t tried it recently, try it again.
Enjoyable little game. Just updating this review to note that it works.
