I love the character and boss designs! atmosphere is very fitting and consistent. The execution animations are really cool. I think my feedback matches what others have already said
Don't know if this is an unreal thing, it prompted me to update my drivers but worked as is.
Similar opinion with the mouse for aiming, although I don't know if you have plans to use it in future mechanics.
I'm pretty bad at these games but I do think the restart adds tension. however current implementation means it's better to just run off to the side and restart whenever you're approaching low health, rather than risk dying.
If you dodge while restarting it keeps playing the animation i think? but cancels the restart
