Thanks for playing! What do you mean by sorting issue? Mountains are fairly rare up until the last level, the RNG in each level is fixed to match a theme.
If I had more time adding some civilizations was next on the plan!
I mean when I place a mountain below another mountain it draws behind it
Oh gotcha! First time using Unity's tilemaps (or 2D unity game) I noticed that too but couldn't figure out how to fix it in time.
