This topic is super old so I'm not going to reprint a whole game introduction here, I'm just editing the top to let people know that this game is now available for free/donations on itch.io

It is not a RenPy game, it was made in Game Maker long, long ago, and as such is only designed for Windows computers and not guaranteed to work for everyone. It does still run for me on this machine though.
It is a hybrid VN/adventure game, so yes, there are puzzles, they can be tricky. Hints on how to solve them, or cheat codes to bypass them, can be found in the strategy guide. And yes, people can and will die in this game!
For a little more information about the game's history, I made a tumblr post about it earlier.
This is a soft launch - that is, I'm being fairly quiet about it so far. I'm mentioning it here, but I'm not turning on the marketing yet. If something goes terribly wrong - if the website doesn't work, the installer doesn't work, the demo won't download, anything like that - PLEASE let me know so I can iron out the bugs.
... Mm, squished crisped ironed bugs.
Oh, yeah. GAME!
