I also bought it. Got pretty far on my first run, past the 2nd boss and up to some really strong enemies with StG 44s that completely destroyed me.

Lots of environmental variety as you go through the levels which is something not a lot of VR games and roguelikes get right.
A bit too much reliance on teleporting in the levels for my taste but maybe that will make fast and aggressive playstyle fun.
The enemies hit hard even early on. It's very forgiving as you get a second chance if you die. The enemies became very tanky for me at the end so I clearly needed upgrades or a better build than the random shit I chose. Multiple health bars, armor and I'm pretty sure I saw a mage revive someone.
Enemy variety seemed okay to me. Archers, different classes of gunners, shields, dogs, turrets, mages, tall skinnies and more. Plus the bosses.
There's some kind of subtle asynchronous multiplayer going on. The early levels were littered with dead noob ghosts like the bloodstains in Dark Souls. Later on you can find NPCs that request items and seem to fight enemies, I gave one a medkit but I don't think it did anything. Found a few dead ones too.
Can't really comment on weapon variety yet, it looks small. The items you find in a run give you secondary firemodes and other effects. One of them saved my life here.
