The screenshots don't really do this game justice, was a lot better than it seemed at first glance.
Good:
-Jump straight into the action!
-Simple but interesting combat mechanics, loved in particular how the mage enemy applies terrain effects that force you to adapt your tactics.
-The plot seems pretty simple and efficient at first, but then gets developed through the banter with the other arena fighters in a quite interesting manner (even if it's the classic "church actually corrupt and evil", I liked what I saw, in particular how the protagonist had their magic core removed).
-Pretty good graphics and music to go along the mechanics!
-That's certainly a way for a demo to end up with a bang.
Bad:
-Some attacks feel pretty "cheap", in particular the mage's flying book that can either go up or down at the last split second.
Great work!
