Theory. I can make 3 versions of Platdude in 3D.
All three will be inside a box area. Version 1 will be a maze-like affair, with a multi layered floor, and 4 walls. Version 2 will be up against one of the walls and will play in a classic platform style. Version 3 will take the whole box area and fill it with Super Amazing Platforming Fun!
.. These were my thoughts when first trying out Blitz3D, 5 years ago.
I soon changed my plan and went back to making 2D games!
Still, the “Up against a Wall” idea kind of made it to the slightly dodgy JNKPlat 3D idea, so at least something came out of it.
