Hello Melody/Amber,
If you see things that you don't like or think you need to correct, the only way to do so is participation. Get submissions points, make tracks of your own so there isn't an issue with something being "too easy". In my opinion, a high score is a high score regardless of what difficulty level is present. If I get the fastest time on the first track of a racing game and no one can reach it then it's still a GOOD score just as the last level would be.
It's not about what's easy and what's hard, it's about you being able to beat the scores under the same settings the previous submitters did. Good luck!
