After jam patch

Hello,

jam ended, but we are still working on improvements! 

Game will be soon available on steam so keep in touch!

What we made in this patch:

Improvements:

- difficulty, game is now easier earlier on, and harder at later stages

- fps wasn't issue, but more fps can't hurt right? We optimized some things

Fixed:

- player movement is now normalized (but average speed remains the same)

- volume slider in main menu now works after game is run for 1st time

- top wall bug (snake tail going thru it) is no more

- lights
