Nice game!
As someone mentioned, my main gripe is that the artstyle is pretty inconsistent. Regardless, the Qtes are pretty fast. If you want to make them demanding, I'd argue it would be better for them to require precision instead of speed (slower ball but with narrower window of success). Of course, this is just a suggestion, you do you.
Another problem I have is that the menus are a bit confusing and in the blacksmith especially text and icons were overlapping and a bit difficult to read and understand.
On the other had, I really enjoyed the environments and the music. The progression is also nice.
