Since you're one of the cool ones who do read developer updates, I will reveal that you can find a suspicious new test mode in Training menu. And you might need someone else online to fully try it out! *wink wink*

• Is it balanced? No.
  
• Is it buggy? Yes.
  
• Will it crash the game? Likely, yes.
  
• Will I be expanding it? Not sure yet.
  
• Am I overworked? Oh, yeah.
  
• Am I hyped about my game(s) having multiplayer? ABSOLUTELY!
  

Hope you'll have some fun with it and report any issues (there will be plenty)! I need to take a break, since I really went all-in with my effort trying to make this work.

Known issues:

• Only host can pause the game
  
• Projectiles don't get synced properly
  
• Kamikaze enemies can sometimes spawn on you
  
• Some (arguably funny) movement glitches
  

Cheers!
