Art and animation is very good. Attacks feel like they have impact to them. There were times when it felt like a lost health without knowing why. Either enemy attacks weren't always clear enough, or maybe try making it clearer when your losing health due to lack of bloodlust.
Thanks! and I'm glad you dig it!
In the future, there will be an ingame tutorial stage that will teach all these, but atm all the info is in the mechanics page when paused, but yeah, if you use a skill with not enough bloodlust, you'll be penalized through hp.
As for the error, i know nothing of macs and linux sadly but the issue seems apparent: https://github.com/godotengine/godot/issues/44226
I only get to export the game knowing its a 1:1 conversion with other OSes but I guess I'm very wrong, so yeah this is a Godot thing that I can't do anything about :(
