Where do you even get the latest version? I can't find it.
it's on his patreon. you'll need to shell out $10 or hope someone posts the download link.
You can also find it on yiff.party
You can get 6 of the 8 endings by simply pressing 1-6. Being too rough on Jesse (spamming spank, electric tools etc.) will also get get you an ending, or game over more like.
Then there's the werewolf Jesse ending which you get by spamming the arousal potion.
How to trigger ending 1-6 by normal means I have no idea, I've managed to get maybe 2 or 3 of them by complete accident.
