Reptile: Basically any kind of level you can make will do since the layout of the level itself might not necessarily be judged with your new game mode. Also, you can edit your own levels or the standard levels if you want.

Toxic Bunny: I might accept that kind of tileset if the 3 themes at the bare minimum each use different colors, but I'm a little more interested in more clashing themes like the one I mentioned in the example. However, if you make a huge tileset but the 3 themes aren't the most distinct, I'll probably accept it anyway.
