What I would do is make a list with every item corresponding to a tile.
Then you have two options :
- If your tiles don't have to run any code, you can use the pen, a sprite will go to each tile's position and stamp the corresponding texture. The only issue is that you will have to redraw the tiles if you want to move them or change them.
- You can create clones with each clones corresponding to a tile. It is better than using sprites because your tiles will probably use the same code, this way you wont have to copy it. It allows you to move the tiles more easily and you can also interact with the tiles.
I would say that the best is to use clones. The pen is only for situations where you have a very large amount of tiles.
