First of all, this is a fantastic game. It was much more fun playing than i imagined from the videos I've seen.
I love the different playstyles of the 6 heroes. Some of them seemed a bit overpowered at first, but once you learned how to deal with them they all started to seem more or less balanced.
Also, the graphics, animations and sound is insane, i can't remember playing a game that had as good a feel to it visually as this game does. And i just love the sound of the Orochi execute when she chops the head of an enemy.

I was lucky enough to not have any crashes or network problems, apart from some host migration now and then.

I'll list a few things i think is missing from the game at the moment, most of them are probably already on your to-do list.

- Practice mode. There needs to be some kind of practice mode, where you can tell a bot to stand still, or fight a dummy or something, something like pratice mode in fighting games like Tekken and others. I'm using a steam controller, and it was a lot of hassle to set it up, since i had to be in a game vs. a bot, and with no pause or anything, it would just kill me while i tampered with the settings.
Also, I had a hard time figuring out how the berserker infinite combo works, and i think a practice mode would have helped a lot.

- Better tutorials. The tutorials for each hero is ok, but it would be a lot better if you could split them up in to more videos, so you can play them one at a time, and not have to look through how to block and how to switch stance every time you want to see the techniques shown at the end.
Also, theres not explanation on how a parry works, I had no idea how to do a parry until someone mentioned it on twitch.

- Strenths and weaknesses of each hero. It would be nice to have a short list of the strengths and weaknesses of each hero, so if you encounter a hero you don't normally play, you have an idea of how to counter them. I believe the heroes already have some strengths listed, but no weaknesses as far as i could see.

- Dedicated servers. This is pretty much a buy or no buy for me, I gave a key to 2 of my friends and one of them is on a Carrier Grade Nat network, since it's the best connection he can get where he lives. Anyways... this means his NAT type will always be strict, and we were unable to play with eachother, which is simply not ok. Also, host migration can be very annoying.

tl;dr: Very well polished game. Needs a practice mode, and desperately needs dedicated servers.

I hope this has been helpfull
Best regards
