pretty late to the make-a-thread party but whatevs.
So the main gimmick of this level revolves around how items like springboards and keys can float on the "cave" lava. I don't recall ever seeing another level with this gimmick (though I suppose it kinda works similarly to the 1F0 levels that are all over the place this contest). I feel like this is the best level I've made for a VLDC so far (this will be the fifth VLDC I've submitted a level for).
Aesthetics are not final. (I'm hoping to add more detail to the ground and change some of the palettes.) And yes I know the background is mess up in the eighth and ninth screenshots. (I've fiddled with the BG positioning but haven't had much success.)
