Hello! Thank you. All the tiles are 16x16 pixels
Well, honestly, I struggle to get anything done, especially if it's just using the green part of the map, haha. Since I'm still a beginner, I'll keep struggling, but I'll make it work.
You can ignore it lololololol I managed to find the hidden tile which is just the green square lololololol
All fine. Glad the problem is now fixed
