Great 3D design of the game. But it's neither new nor original game concept and it's lacking some basic functions in puzzle games such as a clear overview of your progress : where are my perfects and where do i still need to train ? Time losing because of restarting several levels of the building isn't well understand neither. 2.8/5 today, but it has a 4/5 potential.
Sorry but the game doesn't go hard fast enough to my opinion. I'd prefer less easy levels. Nice game with an old concept. It goes well with teaching kids too. Thank you. Keep going.
