A dark and disquieting time manipulation puzzle game.
After coming back to poke at the game gain, there is one situation where I think the conveyance is strange:
1) Put a box in storage.
2) Try to put a box down but there's already a box there (so it's instead put down in the past).
This is now a situation where if you don't pay off your box debt, the world ends, like the more typically used version of 'put air in storage, put a box in storage, box is in the past', but UNLIKE that version, there's no flashing box in storage to tell you what your debt is.
I can't tell if this is on purpose or not, just bringing it up in case this was overlooked during development.
This is on purpose, explanation:
When you try to put the box down, it gets blocked, which rewinds to the initial input and changes it so the box doesnt enter the portal. Now the next time the portal activates it must block that past activation to maintain timeline consistency. So the "debt" is not an item to send back, but the obligation to block that box.
