Lol,it looks the same here, you got me... :-)
It seams to be a bug with the normal generation of my terrain method. But i thought it kinda looked cool so i just leaved it in there.
In another project, the method works just fine...
The "glitch" doesn't really bother me, only the repeating music ingame. I dont know if it changes, cause I dont pay attention and try not to listen to it while defeating the enemies.
Overall, it's still a good game!
