There's also a heavy variant of the game launcher for those who cannot successfully install the DLLs on their machines. It's fully contained, so enjoy!!

I also can't do the "For bubbling, you need to go to the fatum room (accessed with the beast on top of the temple) and sit in the pond for a full minute. The unlock condition for this one is annoying, so that's why most people don't end up getting this familiar. "  is it in the temple or the bryce room?

The bryce room.

How do you get familiar 7? A few of my friends and I have explored everywhere and aren't sure if we missed it in a room or what.

I think familiar 7 is either the bubbling or ghosting u one, either way here are the two solutions:

1). For Ghosting U, you need to grapple the green, spectral grappling point on the island for 10 seconds or so, maybe a bit longer. It's near the temple.

2).  For bubbling, you need to go to the fatum room (accessed with the beast on top of the temple) and sit in the pond for a full minute. The unlock condition for this one is annoying, so that's why most people don't end up getting this familiar. 

I've only found like half oh the rooms but I just love the vibes and the secrets, you should gamemods and maps for gmod !


this is the greatest thing ive played in years

bro where is the peter head.. ive found everything there is to find in this game and its killing me. 10 hours and still no peter head.

Hey how do I get the keycard for the store and the hotel key. Please help me. Also What Does "P" Do?

"P" activates Do-Re-Mi, which gives you a little chart so you can gauge what pitch your character will scream at when looking up and down. As for the keycard, you need to head over to the swamplands with the church and learn more about the wonders of money ;)

Thanks you really active for all your old games and please make a Demon Island 2 Please. When you have freetime of course. Almost forgot how do you get to the peeb room from the photo's from Patron.

where do i get the "socks" or whatever? and i think im missing a few rooms, what do i do with the motionblurr or the screen effects?

i found these secret rooms: the simpsons room, hell, the room in the temple (you stole their toilet)

idk what hacking the computer does
i havent found a secret room in the fatem betula room, or the room where u noclip to see the pissing goddess and minie, or in the giant gman kitchen
what do u do with the ball, or the star of sand?

The socks are a super vague one, first you need to go to a shutter at the front of the hotel and fly or fall into it. It's on the upper right side, facing the hotel from the front. Then, when in the simpsons room, go around the family and jump through the bars of the prison. Interact with the fast homer to access the TIM X room. Then you've got your socks.

Not going to explain the others, but the ball and the star in the sand don't do anything special. 

vidi gaem

g ame is good :) nice

like I mean VERY VERY scary?

Is it really scary?


Really enjoyed this, was laid back and fun...keep it up!
