Hello everyone,

very quickly I'm giving you an overview of the different available versions of 140, as there are actually quite a few with actually relevant differences. According to the year of their release, they're referred to as "2013", "2016" and "2017" although this might not be the year these specific versions had gotten their latest update.

2013: First release of 140. Used Unity 4 (or 3?) Engine. No edge catches possible, some skips extremely hard and tight. Only available on Windows, macOS (32-bit) and Linux. If you have the game on Steam, you can access this version as the "Legacy" branch in the Betas tab.

2016: Update to the game to the Unity 5 Engine along with the console versions. This is the game's version the consoles have. Most skips and early activations still work as well, except the old GameGuy bridge in level 3 is super hard and next to impossible. Eevee skip is a lot easier. Steam version was never officially updated to this version, but GOG and Humble Bundle releases were this version of the game after the console version release.

2017: Most recent update, first available for Windows, macOS and Linux, later also on Nintendo Switch. This includes the introduction of level 4. As of now it seems all early activations of version 1.0 are still possible EXCEPT for the anyway ultra hard 3-4. Cornerjumps no more possible but those are except for nice swag useless anyway. Early activation 2-3 is way easier due to more generous orb catch detection. This is the default version you have installed on Steam. Widows trick at the level 3 bridge impossible but OG bridge works quite well. Slightly different physics. This is the only version which includes edge catches, making it the fastest known available version.

I hope this little overview helps. Cheers!
