this has a lot of potential, but in its current state it's quite annoying to move around. not only i couldn't very used to moving around to the point of being able of predict a bit where i would land, but different levels have different strengths to their launch or something. another feedback is not having only one "active" square at a time, but having a general control which launches all of them. the point of reference could be clicking anywhere onscreen and dragging from there
