The artwork is beautiful and the music fits well. I love the aspect of being able to click the screen to show obstacles you otherwise could only see in the reflection. I think the controls are fine IF - and I think the IF is important - your keyboard has a numpad, since then it's just one row of 3 buttons for speed and one row of 3 buttons for actions. If I were to change one thing, I'd add checkpoints to the tutorial; I died to the reaper in the tutorial instead of stopping before him as I was told, and I couldn't be bothered to rerun the whole tutorial, so I don't know if there was a way to avoid it. I see you're targeting a mobile release for the game, and I look forward to seeing it on the app store :)
