If you use color coded tile maps it can go to 512 x512

I don’t know if you’re talking about how many tiles or tilemap size…
If you’re talking about tilemap size then you can use the overworld extension to combine tilemaps.

> Hey folks! One question I get a lot on these forums is how to make it so that your character can move between adjacent tilemaps. This is actually tricky to do properly in arcade, so I thought I’d make an extension to make it easier (and add a few fancy features while I’m at it). Presenting: [riknoll/arcade-overworld](https://github.com/riknoll/arcade-overworld)! [overworld-demo] This extension is for making games that consist of a bunch of interconnected tilemaps in a grid, much like in the classic 2D Zelda games. You simply create a doub…

If you use color coded tilemaps you can only have 16 tiles! If you use some math and some programming magic, you can make a tilemap as big as you want, you just have to store the tiles as a bunch of numbers representing each tile type and then load and unload bits of it as the player moves around. I’ve done something like that before, though I haven’t really released it yet. You can take a look at my [tilemap data](https://forum.makecode.com/t/pxt-tilemapgen-an-extension-for-messing-with-tilemap-data/33456) extension to see how this might be done, and you could also try to understand [this monstrosity](https://arcade.makecode.com/S92339-45024-80744-41850) which is that kinda unreleased project I mentioned. Maybe I’ll make a tutorial for this sometime!
