I think the idea behind this is definitely ambitious and it does it pretty well. Most of the main problems are bugs with sticking on the side of floating platforms being unable to walk under a lot of platforms, or being unable to jump out of hazards easily (and having to wait until the player dies). The horizontal movement is a little to light so the player character moves very fast. In contrast, the jump is slower, which makes it a bit jarring. However, the gameplay elements are worth the mild bugginess. I really liked the idea that lava can just spew out fire balls and that adds another layer to the platforming. It feels like all this really needs is a bit of polish and ironing out bugs.
