Hi, so im new to this forum as well as python and I decided to create a little game to learn the language a couple of days ago (The game being a cube that dodges other cubes and get score when the other cubes reach bottom of screen. The speed increases at the same time as the score).
The game works just fine and I am looking to improve it. The first improve I am working on is a title screen with buttons. The title screen seems to work (at least I think the problem isn't there), but my game lacks a bunch of features it had before i decided to add the title screen
. Some examples of functionalities that doesn't appear in the "new" game are:
1. The speed doesn't increase anymore even if the score increases (stays stuck on its base value without changing like the code tells it to do).
2. I drew a line in the middle of the screen and if the player goes higher than that line, he is supposed to earn double the score (he doesn't in the "new" game).
My guess is that the problem must be into my bad use of functions though I have no idea where i messed up
. If someone could replie to identifie my mistake it would be really appreciated! 
The next two sections will contain the code of the game alone and the one with the title screen respectively.
