you could add airplane mode that makes you fly in a spesfic level and you need to fly upp while doging lasers and fans and trampolins wich if you touch you will bounce back to the ground and also add levels that make you over heat so you need to get a fan

The overheat idea may be cool but it's difficult to find an interesting way to implement this
Maybe in a volcano, where you have vans in some rock, you have a time before overheating and if you're too slow you overheat and explode (which make you bounce enough to fall)
That could force the player to be fast enough in an interesting way, and can prevent from 30 seconds setup before each jumps
