There is a problem with spawning Cs and Ds. They don't spawn enough times to progress ahead. Also, after the game is over, the game doesn't end, and the lives start counting -1, -2, ... .  I also found out that Clicking on Play Again doesn't restart the game from a fresh start. 

Check out my latest game "Wingin' It!" that I did for the Scream Jam 2025. Let me know what you think.
