Here are a few hints, while playing level:
There are three types of platforms: normal, floating and unstable.
Normal are solid and you can easily land onto them, floating are solid like like previous, but they slightly float on lava, don't worry, you can still land onto them, unstable have a bright shade and after landing onto them, they fall down into lava, and you need to jump off and use wings, otherwise you will pulled into lava, don't worry, they back on their place, after you jumped off.
