This has potential!
Here are some notes:
.) the screenshake shows the edges of the level. either zoom in a little bit or myke your levels bigger (and scroll the cammera to the middle of the level)
.) while the physics based effectiveness of the jetpack is introduced earlier, it is only really necessary to use in level12. So i never used it bc i didnt need it, but level 12 suddenly demands me to have already mastered it.
.) additionally level 12 has a second challenge at the end, so even if i did the first hard part of the level correctly, there is another hard challenge waiting for me at the end, making this level very frustrating!
I would recommend to pace these things out over a bigger amount of levels.
.) up until level 12 the design was pretty dope!
.) if the triangle jumpy things also recharged your jetpack, it would allow for a lot more variety in level design later on!
