Thanks for playing! You did better than me: I made the game, and the furthest I could get was 15.1 days :) The radius, distance, and orbital period of each planet was based on the stats published by NASA for the Trappist-1 system. So those are meant to be Earth days, and if you survived 23.3 days, then that's more than one entire revolution of the outermost planet in the system. Congrats!
