You’re right pictures would have helped, I’ve included some here. I guess i should have pointed out i’m using 8 blocks to form a full “octagon shape”.
When i say 65, what i mean is that there are 8 edges to an octagon so squaring 8 gave me 64 which is 64 variants to a “full octagon” then the 65th would be an “empty octagon”
Gameplay is they are moving at the camera, away from the spawner. Easy gameplay would have more tiles as beams of light will be shining in from behind that need avoiding.
I could make all the levels pre-made but i like the idea of having an almost endless mode as well & for that i’d have to create something somewhat procedural that can generate terrain.
