First of all, the graphics are amazing. It's really a beauty to look at.
I wasn't able to play with friends because I don't have friends, but there's definitely a good game in here. Audio would obviously improve the experience a lot, as would on-screen controls. I had a lot of difficulty with the combat, it seemed like the light attack was actually slower than the heavy attack, but it's difficult to tell. Some more feedback will go a long way. I hope you continue to develop this because you clearly have a gem in the making here.
