Yeah, like the title says, I'm going back to recolor some stuff after a very long time, which it's once I first came to NSMBX if I recall correctly. This time, I bring thwomps on many colors of your choice. You can pick any of them and use it for your levels as you deem may fit nicely.
This could blend well with a certain rainbow world, like having nine different levels with each a particular color lacking a variety. Otherwise, you recolor skills are pretty impressive, I'm going to have to get back into that job here pretty soon, lol.
Keep it up Natsu.
