Pretty cool idea, and I can see a more polished version working quite well, but as of now, it can use some improvements, for example the character controls. Attacking feels weird and unresponsive, at first I was trying to attack based on the direction that I'm facing, which didn't work, as it is based on the mouse position, which it is not bad, but it needed to be communicated better, maybe an cursor could help, or making sure the player face position align with the sword attacks.
The dash felt very weird to use, I don't think inverting the controls for it were a good decision... Also, my player didn't die for some reason, his health went to 0, but nothing happens...
Overall, pretty cool idea. This game has potential, with more clarity, and polish, it can be a pretty good game!!
