lord ferocious would you mind if I post my game breaking strategy? I recently achieved my high score of 97 billion and I'm sure this is the best possible way to beat the game. I'm sure I can achieve more since that run wasn't orient express. I also used to be skeptical how people achieve those amount of scores in gamecenter but now upon finding this strategy I believe they are now very plausible. It feels sad though since this strategy feels like an exploit and I already have that sense of completion. It is still a super fun game for sure and I'd still attempt to beat my high score every once in a while.
here's a hint: (Its a variation of ElectricGrandpa's strategy, but with a completely different build and a little mechanic that you should always give attention to.)
