My girlfriend's grand mother wants a lift to the other side of the country to see a concert.

Of course it had to be this weekend.

Any tips on how could I save time and finish the compo in just 16 hours? (4 hours + 12 hours)

My first idea is to go cheap on visuals and go for an "only-text" or "simple shapes" project. I'm using Unity by the way.

Thanks in advance! :)
