Thank you for playing!
Some puzzles have multiple solutions. Level 14 actually has 2 solutions I know of. But most of them have one intended solution and, probably, a few unintended ones.
Lvl 15 is definitely my favorite. I think you sorta need to use all of the things you've learned to solve it, without it being too difficult to reason through. And agreed, I think lvl 14 is the hardest. I wanted at least one level that really leaned into the use of the overcharged recoil to move around.
