It's finally ready. Can still use some bug fixes here and there, but the most important part is that you can play Quadrablaze with friends!

Multiplayer Features

• Host a Peer2Peer lobby with privacy options
  
• Invite friends from within the game (opens up Steam overlay)
  
• Search for public lobbies (only shows lobbies with the same game version)
  
• Automatically syncs custom ships and colors
  
• Quick Match tries to find any available match or starts up a new lobby
  

Known Issues

• Starting a second round may result in extra bugs. When one enemy bug starts, it generally snowballs and breaks other unrelated enemies. If you find that enemies don't act quite right, you may have to restart the game.
  
• Deformer (enemy that drains your shields) animations may not play on clientside but will look fine for host
  
• Higher tier Exploder (red enemy with blaze ability) can be instantly destroyed when running into them. Gotta disable that later.
