I think I might have borked the level that introduces the checkpoint machine? I took one of the boxes out of this room and now realise that I need both boxes in order to activate the switch:
As far as I can tell, there's no way to get the second box back into this room, and I'm now checkpointed with no way to start the level over :/
Is there a way to fully reset the level? The problem I'm having is that it's not impossible to mess it up irreparably, discover this after you've checkpointed and then you have to do the whole game again to get back to the level.
I'm now up to the final section of this level (which I assume is the last one) and it feels like I might have prematurely used a crate to activate the ceiling switch in the first room, but it's stuck there now and I'm not sure if I have enough crates to deactivate the switch and get it back.
