Man this was really fun. The delight on my face where after failing my first run, deciding to go with the Hot Rod and noticing it does leave a trail of fire, excellent.
The choice of difficulty levels on a per flight basis is great, it adds a little element of Push Your Luck into the whole journey, coupled with the upgrade system.
I did have to double check what a passport bro is and it certainly changes the context for what my guy is doing hopping on all these flights now XD
