There is a community of Replayers/Speed runners out there, and I was not aware old versions were part of online leaderboards. I'm adding this version back in case you need it (v1.1 from 2018).
Notes:
-There is no feature missing in the new version (2024+) that will find in the 1.1 release (2018).
-The save file is shared through steam cloud save, bear in mind starting a new game (From the menu > New Game) from either version will override the level progress (But won't affect unlocks or endings). That being said, the save files are compatible in both versions, so you may not experience any data corruption.
The v1.1 should work as it did back in the day, but I have not beaten it again from start to finish, I'm still having testing nightmares from the last release.
If you cannot launch the old version or get crashes, report them so I can look into them, but remember I cannot patch bugs in the v1.1 as they are addressed now in the v1.2.
Thank you!
