The simple premise really made me play longer than I thought I would. I think the difficulty is a bit uneven though. Sometimes it was annoying to get through a relatively long easy section for a single attempt at a difficult jump.
The artstyle is soulful and the music fits well.
My first fall was partly due to what I think was shader compilation stutter after killing the first enemy. Not a big deal really since it didn't happen again, but maybe something worth fixing if it isn't too difficult.
