Well done! I think this is one of the first online games submitted to SBIGJam, and it works really well! Opening 4 up and hearing the menu music overlap is perfect and I'm all here for it! The fact that it's actually 1 button controls is also really cool!
I guess the closest comparison I could think of was "affordable space adventures" for the Wii U where each person controlled an area of the ship, but the kind of fast paced nature worked really well and really unique. The music tracks are definitely the standout feature, but the concept is great on so many other levels as well!
We should totally try organise a playtest for this on the Discord. Well done on submitting!
