Is there a map available? The world is massive! I have 1 lockbox left in space. No idea where the final code is. I have found 4 so far and one of those is not working, so it might have been a false clue and there is another one left to find?
I also have encountered a strange machine underground (after getting the key in space) that might need parts? No idea where those are.
I think on floor 8 of the elevator there is the ghost thing you can carry for a little while, but everywhere I have tried to get to it doesn't interact with anything. Encountered a snail just gives a "?". There are a few other items that just give a "?" and I am not sure if that is because I have already interacted with them or am missing an item.
These is incredibly imaginative and enjoyable.
