Want to build your own crazy dream-world perspective puzzles? Superliminal now has a level editor available in Beta.
Probably one of my absolute favourite Linux releases this year, Superliminal works on what you see and how you see it. It's all about perception as you move objects around to resize them against what you see, and also line up what you see in the environment to make new objects pop out. It's absolutely wonderful.
When it released on Steam and came with Linux support in November, they allowed the import of any 3D model with the Steam Workshop but that was a small step. Now you can create entire puzzles and levels.
Check out the level editor in action:
Looks like the Steam Workshop is filling up too with lots of objects and levels being created by the community. Given the unique gameplay mechanic, I can't wait to see what elaborate designs people can come up with.
