v0.2.1

Updates:

• Added music
• Added sound effect for crystal collection
• - and + to decrease and increase music volume
• [ and ] to decrease and increase sound volume
• Added volumes to preferences so they are saved whenever they are changed
• Updated saving so that it will save every time you collect a crystal or complete a transaction at a port. This will change over time, but at least allows you to not need to think about hitting Insert if you want to save progress. Remember, you can reset progress by using Delete

Thoughts/Observations:

• I was planning on starting the development for the fuel and hull systems today (got the sound and music added a day or two ago), but decided to focus on building up more functionality around the music and sound controls. Eventually these controls will be built into a settings screen, but for now the keyboard keys work!
• Fuel and hull systems should be coming soon.
• The more I play, the more I want crystals to stick around longer off screen before they disappear (done so for performance reasons). I will probably make the playing field larger sometime soon as well so they dont disappear as quickly.
• I also plan on throwing in a small hack around never letting a port get stuck at 0 credits for the short term to get around that limitation.
