A space game about autumn! What a unique take on the theme! I couldn't find the autumn planet even though I had enough clues to visit the worlds with the ??? on them, it was hard to figure out which planets I had seen or which I had yet to see. Perhaps making a sun in the center and putting all the planets on an orbit around the sun it would make it easier to navigate as well as some sort of marker or cursor saying you have visited the planet. Perhaps also an indicator whether or not you have discovered everything on a that particular planet there is to see, all the hints. Great entry!
