First of all I really liked the QTE mechanics for the combat. However I feel like the difficulty for some of the QTE was really high in contrast to others for no much reward in damage, other than that the combat felt great!
There needs to be something that shows the SP when using the items and if there is one I didn't really saw it.
Loved the Art style and the animations felt really good. The boss needs more anticipation in some of the attacks because they felt too sudden.
I had fun tho, great demo!
