I am wr in this game.
Okay. Honestly, I don't have a Pico VR headset, I prefer to use Meta Quest. Strangely enough, this game is only for the Pico headset, and I can run this game on my headset (I don't know why, probably some kind of bug). By the way, I want to release this game on the Pico game store, and also release it on the Meta Store.
By the way, I noticed that you and your friends are often only in the "Mine" location and sometimes on the second floor (I think). If you didn't know, there are 2 more locations in the game that are at the end of the map! These locations are called "Parking Garage" and "Backrooms". The most interesting location is the Backrooms, because it's the most dangerous and interesting location in the game. It's hard to get to these two locations, since monsters will get in the way.
I can honestly say that you need to use a tactic to get to the Backrooms: wait until many of the monsters go to the first floor, then go into the tunnel on the second floor, making sure there are no monsters nearby. Go up to the third floor and walk slowly so the monster Gus doesn't catch you, since he's blind but hears footsteps. You'll also be hindered by the monsters GorillaScarAshy and GorillaScarSandman. To get past them, you need to lure all of them (including the monster Gus) to one place — put simply, you need to make them chase you and then climb onto a shelf — that way they won't catch you. After you've done that, you and your friends should run as fast as you can to the Entrance room — that's where the Backrooms location is. The monsters won't be able to go into the Backrooms (specifically the monsters Gus, GorillaScarAshy, and GorillaScarSandman), because the door will block them. And there you have it, you've made it to the Backrooms! By the way, I use this tactic when I play with friends, and it really helps.
