Click "See Inside" and edit the green block with the pixel input. You can set it to what ever you want and whatever you drew will pop up when you press the green flag. Repeat this process for every sprite and you'll get the entire drawing, and you can create dungeons with this now! By editing each pixel input in the custom block, you can draw spikes, walls, and the ground! Not drawing anything at all on a spot on every layer will just make it blank. If you place multiple tiles on the same spot, it won't draw anything on that 5x5 grid space. Reposted because I fixed a tiny mistake.
"NO WAY I MADE IT FIRST TRY LET'S GOOOOOOOO!!!" -deadread after finishing the original project in 3-5 minutes "Wha? Huh? WHA? HUH?? IT ACTUALLY WORKS!!" -deadread after finishing this project in 1 hour (I actually timed it with giorno's theme 1 hr) I made my pixel art maker into a DUNGEON CREATOR!! Fell free to remix, but remember just one rule: Edit, but give Credit.
