For those of you unfamiliar with Fez, it's a 2D game in a 3D world.
Basically you can use the newly understood 3D powers to rotate the world around you.
Since Flowlab is NOT 3D, I made a quick and simple concept on how to make a rotation illusion.
Currently, I only made it so you go around to the right and front side of the building.
I could keep working on it, and make an entire game using this concept, but I was only building this, before adding it to Diamondsion Assault HD Beta. Of course, I will actually put effort and transition into the DA version.
Here's the link. 1 is for left turn, 2 is for right turn. I only spent about 15, 20 minutes.
Don't expect much, it is very buggy. Sometimes you need to jump before rotating again.http://www.flowlab.io/game/play/60947
