Wow, you've had a very busy Halloween! Everything has been overhauled in less than a day!
I've been able to get a proper taste of the gameplay now, it's fun and works well as a short game! A small interval between pumpkins especially at the start would help ease players into the action and would prevent situations where moving away from a pumpkin makes the next one hit you from the back. Other than that, I think you've addressed all of the other issues I had in this a large and very fast set of fixes!
