Yay, replies ^^
Excuse the emo comment from yesterday, I tend to get like that when my work isn't noticed.
As for the gameplay, I didn't really expect you to feed me with ideas, and I probably won't end up using the effect as a main gameplay feature - I just want it to add to the game as a whole.
And it's correct as you say, Brog, it's made by connecting opposite sides, and as TheLastBana said, draw the flat view onto a bulging shape.
This lets me use a normal square grid when placing objects (such as the game maker room editor), and the size of the room isn't limited by the area of the sphere.
And Brog, thanks for the warning - When (if) I release the game, I'll add a "Player discretion is adviced"
