Great game, all the grindy goodness of an rpg with all the hands off of an idle game, definitely 5/5. I think I'd like to see a title that's something like "master of masters" for maxing all skills, or having all other titles.
if you get to spin level 9+ or so, get max boosts and max shields, then hit the perfect spin, wait till you hit the ground, boost till you run out and then shield against birds and mines while staying on the ground, you can beat the game.
i got all three badges on my first playthrough, it wasnt that hard if you just do jobs almost constantly and only do schooling and adventuring after about halfway through
