This was a fascinating puzzle game. The core game mechanic was pretty straightforward, but I still had to stop and think about each puzzle in order to solve them. It pushed me to think in 3 dimensions, while still feeling fairly intuitive. It took my a little bit to figure out how best to use the mini-map, but, when I did, I found it to be a useful tool.
There were times when I wanted to rotate the whole cube to see it from a different angle. Using the mini-map helped, but it wasn't quite the same as being able to move the whole cube around.
It wasn't always clear what things would block my path and what things wouldn't. There were a few times where it looked like my path was clear but I couldn't move forward. Other times it looked like the path was blocked but I could move forward. I most acknowledged it on Level 6, when I was able to walk onto the water tiles on my starting block and on some, but not all, of the rock and tree tiles of neighboring blocks. On the mini-map, some of the spaces I could walk on did not look like they had a tile, but it did show the arrows to indicate I could move there when I was on a neighboring tile.
This was a really clever use of the theme. Using a Rubic's Cube as the base to rotate and shift the game field was fun.
