I can't remember seeing this mechanic of (Amount of coins=Jump Power) and I quite like it, good job on the level design, it didn't felt like I had to start from the beginning each time I lost power, good job on the sound track too, its non intrusive to the gameplay and that's important when you have to concentrate on the jump. I found myself fighting with the camera from time to time because of its fixed position, still I finished the game. Good Job!!
