After playing it three times I was about to give up on getting to the end until I saw the edge of your final image. I then proceeded to play for another 30 minutes just so I could see what it said. Well worth the time and effort :p.
In terms of improvement, my personal preference would have been to add a checkpoint in the second level after you made it to the platform after the first water jumping puzzle. Other than that I felt the game was well done for what you had. The game shows that you put a lot of effort into level design, and you did an awesome job building the parallax effect with Pixatool.
I'm looking forward to what you create in the next jam.
