Pretty cool, got lots of potential, BUT, the levels feel a little too big and empty. It'd be cool if there were more things to grind on, and maneuver around in the combat arenas. In the first level it also felt like i had to 'cheese' my way out of the first combat arena. I'm not even sure what is actually intended for that part, but I ended up wall grinding and spamming buttons to get out. The levels also felt like they were scaled up 1.5x, so it was kinda hard to jump onto things.
Combat also felt a little flat, as there's only really two attacks, and enemies tank too much damage, in my opinion.
Ultimately, I think if there was a larger focus on movement and momentum, and less so on defeating huge amounts of enemies in big arenas, the game would play a lot better.
There were a lot of cool things tho. The fact that you could see yourself through walls and it also indicated where you'd land to grind was good. The controls also felt pretty responsive and fluid.
