Created a video of 4 guys playing this together. https://www.twitch.tv/videos/2321063602
They all had never experienced Extreme Violence 1 and asked them directly to play your version.
They all seemed to very much enjoy it! I also joined in the end, plays really great!
You can ignore the screen size changes during map transitions, this is the automatic zoom that I need to adjust the viewport in the emulated configuration (you dont need to fix anything).
PS. Suggestion1: To balance players out and make it more challenging, would you be interested in adding an option that gives the upgrades of the winning player of the previous round to the player which lost 1st or to the player with the least score?
PS. Suggestion2: Team mode? with optional friendly fire on/off?
