This update fixed a lot of bugs and added many new features. Here are just a few changes: 

• THERE ARE NOW VOLUME SLIDERS FOR MUSIC AND SOUND EFFECTS
• New ship added (Check Twitter for a promo code to unlock this - every ship in the game will always be free, but this is to thank my Twitter followers)
• A field for entering promo codes was added (Again, microtransactions are against my philosophy and will never be added and all ships will forever remain free)
• Locked ships now include a "Locked" icon to indicate that they still need to be unlocked
• The ship screen is now easier for me to add ships to - it is automatic. It is also now part of a scroll field, meaning it will scroll when new ships are added
• Unlockables are available for all ships (instead of select ships, as before)
• Resolution changes were implemented (but are still being worked on - in the next update being pushed out asap, a known bug will be fixed)
• Ship stats were adjusted to be slightly more powerful
• Unlocked levels will be the only displayed levels in the menu

Known bugs:

• The lives meter does not display correctly on some resolutions. This is already fixed completely and will be pushed out asap. 
• The animations for some ships may be broken
• The menu may lock up in some cases

Things I'm changing in the next update:

• Obviously I'm fixing the bugs (Have fixed #1 and #3 at the time of writing this)
• Fixing resolution issues (things will display better)
• Small changes to ship stats are bound to happen, especially with the new ship
