I had so much fun with this! Love the concept, the lore, and especially how the goal changes from early => late game (being able to damage The Cloister is a great idea). SFX + VFX make the hits very satisfying, too.
I noticed that once I was fully powered up, the game ended when The Cloister was at about half health or so. Wasn't sure if it was intentional (i.e. maybe there's a max game time to prevent players from getting too overpowered). Still played it twice to see if I could get to it quicker haha.
Awesome job as always :)
