Oh this was a joy to play! Using the keys to literally make platforms is such a neat way to make you think about exactly what you have to press, actually pressing it and creating a little tune in the process. Up untill I died i did not acutally realise there is no floor, or rather that the floor kills you what with it being the same colour as the floating blocks. I think with more polish and variations of the core loop this would be a really neat game!
