Not sure if the actual game designers working at Jundroo read this forum, but if they do, here's something I would like to suggest to be added into the official game (no community mod for this, it is definitely something that should be in the official game). The game should have LAN multiplayer versus mode. This would involve either a separate server.exe (dedicated server) or an "Open to LAN" button in the game like in Minecraft which would allow others to connect to your game already in progress. Like in Minecraft, it would then do a UDP broadcast to the LAN that a game was being served. This UDP announced server would then appear in a list of available servers in a Multiplayer menu. Then, anybody connecting to your router could play your game, so you could have your friends over and have them all battle it out in the skies. Alternatively for connection method, if it didn't use UDP broadcast for announcing the server, you could still have your friends go to a "connect" button in the game and then type in the LAN IP address of the computer hosting the game (easy enough to find if you use the "ipconfig" command from the Windows command prompt on the computer hosting the game). Either way, this would allow for you and your friends to come over with their laptops and copies of SImple Planes and then battle it out against you and each other on your LAN.
