Cute graphics and nice concept! Hard to figure out what do.... I still don't know if I got it. The onscreen controlls threw me for a loop, was mashing qwerty to try to find the buttons.
Thanks wanted there to be an element of a puzzle for the player to work out what to do to remove the different obstacles but I guess that can be a bit confusing. You should be able to use both the on screen controller and keyboard arrow keys or awsd.
