Disclaimer, I couldn’t play because I’m on Linux :( But I took a look at the video gameplay and speedrun.
The idea of using your past self to create a path to finish the level was something that other games have explored as well, but this is the first one (that I saw) that does it in 3D
And I think you do it pretty well! There’s a pretty fair mix of mechanics here, playing around with the path that each personality leaves behind, but I think most of it plays as a puzzle with a pre-made solution right? I think there’s a lot of unexplored potential here, something more along the lines of “Mosa Lina”, but of course it still works with a “figure out how to reach the ending with these fractured personalities”, it’s definitely easier to do it this way during a game jam!
It still looks like a good game, and y’all being able to speedrun it just shows that it’s probably well built.
