This is a terrain builder I programmed (the same in my game "blocked defense"), it makes up a terrain based on water and grass. There's a total of 172 800 randomized pixels, making it pretty much guaranteed you're the only one who saw that exact terrain. If I did my math correctly, there's a 0.00000000334894% chance of getting the same terrain twice (you would have to run this (on average) 29 860 194 569 times). Use Turbo mode (shift while you click the green flag) Use space to toggle pixel count
Thanks to my friend Justin for the idea of a terrain builder.
