A couple of the included maps aren't too great. Tropical Island, especially, has a really asymmetric and confusing layout. Way too much of the level is tiny (sloped!) platforms over a big death pit and there's also some bad texturing (especially near the beginning). Granted, it wasn't designed for this pack, but I don't feel like it really works for it. Central City's skybox is very disorienting as well. Most of the maps are playable, but rather bland aesthetically, especially Volcano and Yellow Desert.
