You got my attention with the name, and I stayed because it's just so good, my most sincere congratulations! I haven't tested many games yet, but I can say that this one is my favorite so far, and I'm not afraid to say that's one of the best ones submited this year! 😁😁
I really love how the physics work and how well they blend into the gameplay without issues or weird artifacts, your game is incredibly solid and it ciments a very good base to expand upon! 😃
As a matter of personal preference, I like when 2D platformers include a mechanic to jump higher when you press the jump button for a long time, but it's just a nice little addition in my book, and the way your game is made, it's not really a necessity 😛
Keep working on this gem, you have a great prototype in your hands! 😊
