A valiant effort, especially considering that you had a bit of a hiatus from game dev until recently!
I think the overall concepts and ideas that are present in this game are a really solid foundation for an interesting walking simulator type game. Having the level change based on the path that you take is always an interesting trope in video games, and with the narrative theme for the game, that trope could work very well (sort of a Matrix-y/Inception-y type play through).
It's pretty clear that you did not get to implement everything you had planned for in the game, but it's easy to see what you were trying to achieve. I think with a bit of extra time this could be a really engaging experience, you should definitely consider doing a post-jam release of the game.
