Hello! Every now and then i still get asked for old versions of the game. I added a list of the original download links to each version on my website (as Game Jolt still lets you use them but makes them basically impossible to find..)

i haven't tested them all individually so if there's any issues tell me. But it should work.

(also... if you haven't heard... i'm revealing the release date for my original puzzle game later today https://www.youtube.com/watch?v=vazbU4dLfeo ... be there)
