Games That Werent - Cancelled & Unreleased Games | Subtraddition (PC) @GamesThatWerent | Uploaded November 2020 | Updated October 2024, 5 hours ago.
A neat indie development for PC and potentially others which was sadly cancelled early on by Sacred Square Games (scaredsquare.com/). Subtraddition has a cool block mechanism to get you around the levels and solve certain puzzles, with a GameBoy art style.

The game is covered in the Games That Weren't book (http://www.gtwbook.co.uk), talking to its developer/creator Stuart Lilford, and covering a title from the indie community, showing that cancellations can occur anywhere, no matter the size of the game or studio in modern times.
