Update - added some improvements after FFSJam feedback

We got valuable feedback from Finally Finish Something Jam 2022 and here comes an update with some of it implemented :)

Here is what changed with this update:

• added a "continue" button to the game over screen
  • so it's faster to restart a game (you can also use space or enter for this button to be even faster ;) )
• the crt effect is now turned off by default
  • the effect can be enabled in the options menu (ESC to pause, then select options)
• in addition the crt effect was reduced
