Cute idea Mango!
I got stuck on Level 3 a bit because it was janky. you're supposed to place the trampoline on top of the spikes but it kept falling off.
The music stopped playing in Level 5 (maybe it just got to the end and didn't loop?). I also don't see what you need the second trampoline in Level 5 for.
Level 6 is a troll and not supposed to be beatable, right? (:
