See README.md for more info.

I thought it would be neat to make a pretty large tile array. Like 40x40. But it bogs down after quite a few tiles. I assume this isn't affected by the optimizations I already merged. So I'll wait and see when I merge them all together.

It doesn't have to be performant at that scale to be merged. So I'll merge it. I just wanted to note that.
