Hi, is a version history available? I see six versions, from 1.0 to 2.4.
If you mean the differences between each version, I couldn't tell you. I made this game some 7 years ago; I don't remember the differences between them all, I just uploaded every build I had.
I'm sure the earlier versions are shorter and more buggy, at some point I added the intro and the pause menu, etc. But you'd have to play to find those out.
This is a really simple "game". Just play version 2.4 if you're interested. If you're curious what changed after playing version 2.4, then you could try version 1.0 and see all the differences, and then more from there if you're somehow still interested. The game is only a couple minutes long even in its longest version 2.4.
