Great concept, but I'm doubtful about the execution.
The controls are not following the screen orientation, and the light is flickering: I'm not sure this kind of shader suits the limitation. The kind of synchronized moves seemed laggy (but maybe it is because I am a Crypt of the Necrodancer player), and sometimes I died without any visible reason. I got stuck in the third level by getting killed again and again by nothing :(
But the idea is still good, and the game would have looked much better without the limitation!
