The first playable version of Decay is now up for download! I very much consider this to be a work in progress, and I appreciate all criticism on the environments, themes, puzzles, etc. There are still a lot of visual tweaks and optimizations to be made to the map. I plan on working useful suggestions into the mod in the future and patching them in.
I'll also be updating the screenshots in the image gallery to reflect the visual changes in the game.
