ive been looking around myself, its like cosmo pickle just vanished off the internet?
kinda worried about them to be honest

Its still being worked on, as far as I know theres a new version in T-Hoodie's patreon

if you got the 4/20 orgy image then you got the star, its designed to have locks and stuff on it

there shouldnt be any other requirements, just beat custom night will all animatronics set to 20

there was a browser version, but it just sucked, probably why  the dev removed it

it can, you have to beat 4/20 mode in custom night

your missing golden freddy most likely, easiest way to get her H scenes is to put 6 9 6 9 for custom night, theres also the doughnut, just click on it multiple times and you'll get the final animation

there are some fake walls, both of which are above the area the water zone items are at

its a Known bug, dev put it in the known issues section of the description

the last time this game was updated was in 2018, there is a very, very low chance a mobile version of this achient game will be made.
