Interesting and original concept. There is some lag between tap and result, but it can be considered as a feature rather than a bug. As a pro tester, cannot fault the game
The game does not move forward correctly. There are so many times I cannot see the cubes ahead and have to guess where the stick might reach. Fix it as it kills the game play
that is the difficulty level of the game.
Got it free on discount. Small ad on bottom, which is not disturbing and you may watch ads if you don't want to restart the level. Not happy for the ads, but seems not disturbing/optional.
