It is very nice that the game works on Android with a controller, but there are some places where the controller integration could be better. Specifically, the puzzles with the wasps on level 5 or 6 and the puzzle with the balls on level 1 are difficult to control properly with a gamepad.

Thank you for the feedback, you are correct that we need better controller support for NVIDIA Shield and other devices. We will look into improving it for those specific puzzles.
