Wow! This is an impressive game. I love the 2D/3D look with the drawn art. The audio works well, and the voice acting is a great touch! The combat is simple, yet very fun. Getting the rhythm of striking and dodging is challenging at first, but fun to master.
I managed to complete a loop after several failed runs. The boss seemed glitched when I fought it, the sprite seemed like some sort of texture error had occurred, looking like a mis-scaled and offset texture rather than discernible artwork. I found one other bug with the boss.. after defeating it, if you keep striking where it fell, it'll reappear and play the "defeat" animation again and again.
Overall a really awesome entry. Great work!
