I enjoyed this. The art and music are amazing. Sadly, the controls are a bit awkward.
It's quite difficult to do precise movement - this could maybe be rectified by having her take a second or so to reach maximum speed? Also, the rate of falling isn't consistent - when going left or right you fall more slowly than when standing still. This might be intentional, but it feels awkward.
I'd appreciate a Linux build when you get back to this. Looking forward to seeing more :)
