This is a super cool take on the concept of "breaking." You're making good use of the palette - the player and the other relevant objects stand out well from the background, and the dark blue colours really sell the idea of the prison too. Doesn't seem like a very nice place at all!
I liked the puzzles overall, and you're playing around with the central mechanics in interesting ways. Some mechanics aren't super intuitive, but I think that's fair for a puzzle game, and the tutorial does help. A few levels took some trial-and-error, but in hindsight the solutions always made sense.
I did find the game a little hard to control at times. I had some trouble aiming my jumps, with the character often slipping off ledges or not quite making it over walls, and I occasionally dropped turtles on my own head and got stuck under them. The game is mostly a puzzle platformer, so it wasn't a huge problem, but perhaps the physics could be toned down a little.
All in all, good job! This was a neat experience.
