V 1.6 - In Space, Everyone Can Hear You Jammin'!

Finally, the music update has arrived! No longer must you sail the stars without an upbeat soundtrack! I've implemented about half the songs I would like the game to have. I want to do a couple more boss themes, and then some fanfare hits finishing waves, game over, etc. 

Here's the changelog!

[ADDED]

• 7 new songs! 4 for stages, 2 for menus, and a boss theme

[CHANGED]

• Reflector is now bound to SPACE as well as C. Use whichever is more comfortable for you.
• Shortened the length of the Spider waves, increased the length of the Blade waves, and tweaked the balance of Angel waves
  • After repeated testing, I found that the Spider wave was both the most boring and longest wave in the game. They've had their length cut by 30%, but their spawn rate was also increased to make it a little more exciting.
  • The Blade wave often came and went too fast for my liking. I've been meaning to implement this change for a while now.
  • Some of the Angel waves were too easy and didn't differentiate themselves enough from previous waves. Hopefully it feels little more lively now.

[FIXED]

• Fixed a bug that caused the controls and high score readouts to sit on top of each other after having cycled at least once
• Fixed a bug that caused the relic icon to appear in the wrong spot in the Shop
• Fixed a bug that caused two final bosses to spawn
  • This one was a hilarious surprise when I found it: https://imgur.com/a/87iW1oz
• Fixed a bug that caused the game to crash on certain Angel waves
