0.5.0 is here

What's new:

• NEW STAT AND PICKUP!
  • It's called PRC (Pierce)
  • It lets the player's bullets phase through enemies to damage more enemies behind them

• COMPLETE REBALANCING OF THE GAME!
  • Enemies now die in 1 hit but beacons spawn them faster
  • Replaced decimals with full numbers in most places (though this might be reverted)
  • Much more!

Other things:

• Recolored existing pickups
• Fixed z indexing
• Fixed bug where two beacons would spawn in the same place
