House of TG is an ADRIFT port of the original House of TG game by NandiBear.
Well let's start with the basics, you are Leo Guy and you are a thief. Not one of those skanky smash-and-grab crack-heads, but a professional second-story guy, just a few dollars short of a gentleman thief.
So when you found out about a score to good to be true (and as it happens it was) you just had to check it out.
Seems that some overnight millionaire (selling some strange naturally red leather) had got their hands on a rather large and expensive gem. And a few days of surveillance shows she has no security on her rather swanky pad.
You were rather disappointed about how easily you got in, she hadn’t even locked the door, and so what happened next was a complete surprise.
A voice from thin air:
"Ah my little thief, did you really think I would let someone steal something so precious?
I’m a generous woman though, I’ll do you a deal: if you can find the gem then I’ll let you escape. If not, well let me say this place will change you!
So look around, enjoy the amenities, get comfortable in your (new) skin."
And with that the door, the DOOR disappears.
