I liked the game overall, it is a very good idea, though it did seem very frustrating for some reasons:
- The "Troll" platforms were way too unnecessary. I mean, why? The first time they appeared was okay because it felt like a choice, but then it started to get really unnecessary.
- There is no "Coyote time". What is it? In most games, there is a small window after you fall from a platform where you can still jump. In your game, the lava kills you instantly if you don’t jump in time. You could implement something like a 0.3-second grace period (or adjust it as needed), because right now, it feels like even though you pressed jump, it didn’t register. I have found a video that should help you understand Coyote Time if you don’t know what it is:
