Went for something a little different on this run, I wanted to max everything out but not use any UTs and see how much longer it took. The combo multiplier maxes at 6 so you can still get a decent amount of money going for them it's just trickier than using UTs.

Anyone who guessed it wasn't possible needs to do their homework on just how much money there is in the game :)
