I've come across an interesting game, but I'm not really sure if it's eligible for this website.
Dweep Gold is a fun, but obscure, shareware puzzle game released for Windows in 2000 (I think), and created by Steve Pavlina.
The game's developer
outright states that since 2006 the game is discontinued, and no longer available for sale anywhere. So it would mean that the game is "abandonware" in every meaning of the word.
That said, I've only managed to come across a full version of the game on a file hosting service, presumably uploaded there by some pirate. Is it still okay to upload it to Abandonia? (It's not changed from the original in any way as far as I can tell.)
