I love it!
The aesthetic is super cool, and the gameplay is fun. You've leaned in deep into the hyper-stylized craziness, and it certainly paid off! This is awesome.
I like the combo/heal system. Really incentivises blocking, which is always fun. It does feel like dodging is not as important because of the system though.
The UI is a little confusing. The top bar is obviously the boss's health, so that's clear, but the left and right sides are weird. Because they're the same but mirrored, I thought the boss also had a combo bar - I didn't realize it was my health. I think putting both bars on one side would help cement that they are the player's, and I think changing the design on one would help make it clearer to the player.
I love the sound effect and style on landing the ultimate on the enemy. Wish every hit felt that exciting.
I really really dig it, this is a very solid fighter! I couldn't beat the boss though, he has a ridiculous amount of bars!
