Snake tutorial tilemap image is confusing

It eventually asks us to draw an outline, but the image it shows has grey tiles, when the tilemap we're using has white tiles. The issue is corrected in the followup image, but was definitely confusing for me as someone new to the engine and new to tilemaps.

Might post a PR later this weekend if I can get a good image :)

but the image it shows has grey tiles

Isn't this while the tile palette is open? I think we grey out the background a bit when this happens.

Yeah I think that was the confusing bit. It also looks like the better image has a score counter that's never referenced in the tutorial. Overall, just rewriting the tutorial a bit to take the images into account would be good. I followed this tutorial as my very first intro to Defold, so maybe I was missing some assumed context, but just wanted to share
