Here’s an amusing thing I found @grazer
A few years ago, you let me test a special version of flowlab?v=2 (Which is now ?v=1)
Apparently this version still exists and my game was locked in it, but I could force it to ?v=2 again to the current version of flowlab. The neat thing about old flowlab was the brush tool. Here’s your chance to see a bit of old flowlab for you new users. If you try to ?v=1 any current game, it will obviously brick, because new flowlab is much different. Old flowlab can still load in ?v=2 as long as you don’t change anything. I did this just to download the sprites from my older games.
