Thanks a lot for very constructive feedback! I wanted to add something in the game to prevent buying a ton of routes between just the two planets but sadly, I ran out of time. I really like your idea of each planet having different unlockable skills! Regarding the music, there is music in the game, maybe I have made it too quiet, I haven't really tested it since it was a last minute addition. Again, thanks for the comment, it is really appreciated!
