I really liked the idea, though I'd love to see more variation through the gameplay. You might even achieve this by changing the background/graphics as you go, to give a sense of progress, or add variations to the mechanics (like add a rocket that follows you or something). The physics could use a little more polish, to give out the momentuum of the original game. But I did enjoy it! I like that it preserved the shop mechanic from the original :3
Don't give up on your motivation friend! Your game has a lot of potential! A few tweaks can make the playability much smoother, and you can always ask for help from the community if you find yourself stuck. Keep it up!
Also, the suits are a bit expensive. You could make them cheaper, or add more coins throughout the levels ^^
