Customer Reviews

Great game

I love math music and video games. It can be very strategic when playing at higher difficulties. The only problem I have with it is there is no way to see your previous scores for each level and each difficulty. I would like to see my progress in this great game.

Very first level unfinishable

The squares in the very first puzzle cube did not add up to a multiple of 12. I ended with 5 squares left. A 4,3,1,1,1. For a total of 10. Could find no way to go back to the menu or even quit. Had to force close - and uninstall.

Severe Bugs

Breaks immediately after tutorial with unsolvable puzzles.

Cubes needed to make 12 are not present. No DNA strand found, even on subsequent replay of tutorial. Cannot be played.
