New version released, with some bugfixes and changes based on feedback after original launch.

• Biggest complaint was the fact that it was easy to lose your balls among all the coins flying around. As such, I have found some less circular treasure in far-away lands that will hopefully alleviate the issue somewhat.
• Two new power-ups added - Hexaball and Octoball! More balls flying around, for increased chaos!
• Pause menu now shows current level and loop.
• Overall sound volume was reduced, with title music and gunshots being the biggest offenders.
• Localization no longer reverts back to English when you return to main menu.
• You can no longer destroy nets with your cannon.
• You can no longer lose lives on the very first level  - so you don't need to restart if you mess up right at the beginning. This, of course, does not applies when you revisit the first level after the game loops.

I have added a Linux version, but I can't test it right now so I have no idea how it works.
