Played through more of boneworks, looks like 7-10 levels, design feels pretty old school, you can blaze through in 5 minutes if you know where you're going but there's plenty of little secret rooms and winding paths. Puzzles in actual levels amount to "push these physics objects around to make a path to walk down" or "here's a door that needs a color-coded key, go find it"
I like the idea of using ammo as currency for the shops, but they're only stationed at or near the start of levels and the stuff in there is either guns that you'll get in the next couple of rooms or guns that cost thousands of bullets, and you lose them at the end of the level anyway. Maybe if there were more enemies in levels or a boss at the end it'd feel justified but as it is I'll just find one of the 4 pistols lying around in the level somewhere and double-tap all the drunkass stumbling zombies and headcrabs with that.
But even with those niggles, it's still one of the best VR games I've played yet, and feels the closest to a "real" game.
Can't wait to see what speedrunners do with it, I can imagine things getting pretty crazy.
