Okay, how do I even describe this?
You are a constantly rotating dash over a grid of dots. You are always touching one dot and rotating around it, with one end pinned on that dot. While rotating you touch other dots within distance. When you touch another dot and hit the button, you attach yourself to the other dot. You can change rotation direction using another button. The goal is to reach the point that has a star. As a subgoal you have to touch every point on the grid. To spice things up, other dashes might be rotating that you shouldn't touch, as well as some obstacles.
There. Did you get all this? No? Thought so, so go try out the game, it'll make sense in 10 seconds!
