Wow, the audio in this game is top notch, really well polished art-wise too! I love the Boss sprite and animations
For constructive criticism, the souls moving randomly was kind of frustrating; they would die on the spikes on level 2 before I could kill them, and the timer mechanic sort of works against this because I would need to wait for them to spawn. I think the timer could be relaxed a little bit. I do appreciate how the scythe would repath to kill souls though :)
