Holy crap I'm not even a gamer and I wanna play this. (perhaps that the point?)
Hahahahaah... "Cheese: 10%"
It's a "secret" I suppose. You can get a sixpack of beer on the corridor to the left before the "Exit" hallway (you need to get near the "Exit" first, so the wall will open).
You can see that in this video at 1:20: https://youtu.be/107QBE3EBys?feature=shared&t=74
The ammo panel also shows "Gin" and "Water", but I think those are not actually in the game.
i could not possibly approve of this more strongly
So instead of firing the gun do you get to toss the wine at paintings, to ruin them and gain points? And if you explore enough of the gallery, do you find a bowl of soup on the lfoor, and you can pick that up and then go around making paintings additionally nervous of soup attacks? Just wondering here
i have so many questions too
I can't help but roll my eyes at all the people heaping effusive praise over the Doom Gallery Simulator when it's at best a facile easy joke that's been made a billion times before and at worst just completely misses the mark about what's wrong with gallery culture while also throwing museums and other institutions of public art under the bus.
