now just make things pop up on the land as you add them, like grass, trees, mountains and even lakes, all based on how many land is around each tile
nice, i liked that, can you try to add a hotbar? like you select grass, sand, snow and other base tiles, and based on the tiles around them they change what is on top
not to ask too much of you, but if you do want to make more complex things i can try to help you, i am a programmer and mostly use unity, but i can try to describe what you need to do for more complex features
