Small post jam patch

Now when the jam is over here comes a patch with some bug fixes and balance changes:

• Towers now drop 50% of their worth when they get destroyed. This is in order to make losing towers less permanently devastating.
• Tweaked the wave's spawns in order to be a bit easier.
• Added a new music track when you lost
• Fixed the bugged last round
• Added clarifications in the mom's dialogue in order to make it more obvious that you can attack the lizards.
• Fixed the secret debug button (o) causing issues on the first wave

Thanks for playing and voting! The game placed #109, and a steam page is now well on it's way, expect to see an update regarding that in the coming days!
