I couldn't get very far but I enjoyed what I played of it. I couldn't get the hang of jumping, so maybe you could add some more control options. Good job though and I might come back to it!
I quite like the concept of using more keys as the game progresses but I couldn't figure out how to get past the blue blocks. I was able to get past the red blocks by holding down G, but H didn't seem to anything for the blue blocks. Good job though.
