Straight forward game. I think that the music fit the tone very well. My laptop is kind of crappy, so there where a lot of sudden frame rate spikes resulting in me running straight into spikes and not being able to walk and attack at the same time. Needed a few more retries than usual.
I'd love it if you made a few checkpoints and maybe had the companion a bit earlier/had more tasks before the end, since that part was rather short. Character sprites could use some work, but you probably know that already.
