Suggestions:
Add Parallax for the bubbles on the sides of the screen.
Make the tutorial text animated and with a larger font size.
Make the tutorial optional or not appear after the first launch of the game.
Have the game speed up over time to add difficulty.
Special Platforms that launch you higher than normal platforms
Bugs:
There is a bug where colliding with the side of the platforms will continuously push you down off into the abyss.
Overall: 10/10. CRAB PLUSHIE WHEN?
