I don't understand what the goal is, or if there even is one. I can't really do much other than fly around, and there are a lot more than two buttons, so I don't totally understand how it fits the theme. I think you should've focused on making a high quality, polished, but singleplayer product, rather than a lacking multiplayer game.
Despite my opinions on the game's quality, I think it has quite a bit of potential, good work, and good luck in the jam!
