Once again, another prototype name. Check out the work I did with colors. The bubbles are even animated like in the Pokemon GYM (and I didn’t edit or overwrite that at all). I’m going to give every cave in Naljo they’re very own tileset. I’ve discovered how to add tilesets too, so far, a total of Four tilesets have been added to the game, without overwriting old ones, and you can expect many more. Also, when you walk around the cave, the screen sometimes shakes, because you are technically in a volcano that’s about to erupt!
