This was a really unique gimmick - thank you for the walk through because there is no way I would have put two and two together on the timeline mechanics, but I think that just goes to show how inventive it is!
Great job on the art and the models, they're really stellar, and considering that you did all of that, its a wonder there's even this much in the demo to begin with!
And the story is really interesting, would love to just read the script as if it were a novel, in all honesty.
I also encountered the freezing bug, I noticed it had occurred when I picked up the bottle and then the wrench in quick succession after jumping into the timeline, not sure if that might help pin down the pesky thing.
But great work and amazing concept, would be great to see it expanded, if you can find the time after the jam!
