I will be releasing a new version of the game, probably before Wednesday, which will contain a new terrain generation system. This terrain generation system should create more realistic terrain than the current system. Currently what I have coded in is 4 perlin noises stacked on each other, with an erosion system to create valleys and plains. There are some glitches in the terrain, but I should be able to get it smoothed out quite soon. Also I'm planning on adding a settings menu, but that is dependent on much time I've got.
