Very cool! I wasn't in the jam, so I can't vote but if I could I would give it high marks! At first, I struggled a lot with the boss fight, but the more I played the better I got at reading the tells and dodging the attacks. Kind of reminded me of a souls-like in that sense. Also, it goes without saying the animations and 3d art are incredible given the short time frame!
If I had to leave some constructive feedback it would be that the boss's tell when they are about to stomp is pretty much impossible to see when they are facing north. Other than that though, this was a very rewarding and fun little boss fight you made!
