I liked it... but it was a bit too random and frustrating in spots. I did not get through the first arena right now. The sword mechanic is magnificent and I love EVERYTHING about that. I think the camera could be zoomed out just a tad, it's more frustrating to just get smooshed by an enemy seeemingly at random then to have some reaction to their movements. Careful with the "random" vs unexpected obstacles, it's confusing in spots why I am falling!
Overall, super cool! I will come back to this later and try to finish.
