This was a fun little puzzle game! I got stuck for quite a while on the penultimate level, but I worked it out eventually. I liked the sound effects and the simplicity of the death methods. Having the number of phoenix feathers collected flash when it wasn't enough to go through the end-of-level door was helpful. The one tweak I'd suggest is to either sync movement to the grid, to widen the hallway, or to auto-correct the sprite position when necessary: there were several times that I was unable to get into a hallway until I walked away to "bleed off" some of my positioning on the axis perpendicular to the hallway, so that I would stop running into one or the other hallway wall when trying to enter it. Overall, nice and straightforward!
