The game has a soothing, popping bubble wrap kind of quality... I would prefer that the exchange rp for money/gp weren't buried in the other researches, though.
I think that a "perfect jump" is a jump that lands all of the coaster on a given track...not one where I just barely make it to the next track. That is a "near miss" jump, not a perfect one.
While I appreciate the achievement flag thing in the corner popping up whenever i receive an achievement, I would very much appreciate it if it didn't cover up the donut shop buy button. Currently, it covers about half the button and thus half the price--very annoying when one has just reset the game (I mean sold their business) and is in mass buying mode to get everything back to where it was pre-reset.
