Rooftop Tolls

It is a short and easy puzzle.

You need to find a key item to leave the area. Someone has it. But they're not gonna budge until their problems are solved. It's a simple game, where you help each denizen of the area solve their problem, and in turn, offering you something which could help someone else's problem. The puzzle isn't too difficult, and you could probably solve it by brute forcing choices. Still, it's a cute and fun puzzle to solve.

The art is pretty nice too.
