Don't just tease us give us a name!
It's half sword, but it's barely a game now, more like a tech demo, devs said that they are 1 year away from even entering early access, so less than an alpha build with barely any content.
It looks silly in video because the game use a dynamic, physics based animations system but the gore system, damage system and hit reactions and audio design are some of the best you can find in a melee game, you are gonna feel bad after some matches
Also, you don't have buttons to attack (except a kick and a grab button) you move you weapon with mouse\controller stick so the skill ceiling is basically infinite, you can look like a moron flailing your arms or use actual sword tecniques like advanced guards or parries to fuck up the enemy, the difference in visual between a skilled dude and a noob is 50x times higher than polygon journalist trying doom and watching a shroud match.
Oh and don't max out the graphic, the game is super heavy and kinda unoptimized, you can download the demo that is basically like a roguelite mode or the playtest demo that has 1vs1 with various weapons and armours or different modes like 3vs3 etc, i only play with the playtest, much more fun and people are trying to make records of successive kills etc.
The whole thing can glitch and have weird physics or the damage system not working as intended but like i said, it's in its infant phase still, it's already a miracle that an indie studio can do what they have done already.
