Trick to getting Hard Achievement: Put 2 in height, 1 in fuel. Reset until you get a lucky run, (you want to get purple coins and a good amount of launch time/height).
Put 2 in radar, 3-4 in fuel sucker, rest in fuel tank, remaining into height.
Pull down to bottom of screen for max height launch (even though you go down and bounce, you get more height from pulling down)
You can get a good day 1 run and finish on day 2 easily.
I glitched the game somehow with casting the lightning single target spell which constantly gave me xp (I could put in stats) but couldnt cancel out of the spell so I was trapped and had to refresh. :/
