I would love better ways to seperate areas and allow us to determine what changes are persistant and what resets off-screen. I ran into a persistance problem again in my new level but solved it with the transport pipe glitch. (You can place them on top of each other to direct you to a different location than where you came from)
Underwater levels don't get enough love, so I decided to make a story / puzzle one.
Sunken Castle: A time paradox? EC72-0000-00A5-CC52
Travel back in time to find out what damaged the castle hidden at the bottom of the sea. The castle is riddled with time portals. You'll need to use items from both the past and present to get through the level. No checkpoints this time as all pipes and doors are already in use. Features 4 small puzzle rooms represented in both time frames.
The preview should actually look like this
Can't hide the rooms unfortunately and I had to duplicate part of the level for the illusion of still being at the castle when reaching the finish.
