It's great as a time waster until making all levels now it's boring...oddly I made it to mathematical genius (hard 21) before scholar (practice 2)
Game is awesome and the developer responds quickly
Very well done and enjoyable. But doesn't appear to save state - left the game to check an sms and score was reset to 0.
Not too bad.
Simple but fun. Thanks dev :) Can we have a cursor so we don't have to erase all to make changes and a pause button please
Cool, easy is easy, hard is hard, it's fun.
