Well golden me idol, isn't this a treat! Wishlisted on steam.
The navigation in time was a bit cumbersome though: hope it's a bit easier in the steam game, if that one is bigger.
Yeah this was part of a game jam whose theme was locked doors. So my interpretation of that was having a bunch of open and closed doors that you need to shift in time to get through.
The steam game is cleaner since there's a proper map, and a defined 'overworld'. So you can travel via the entire overworld contiguously and then explore whatever memory is in each room if that makes sense.
