I managed to get further than I thought. You notice the gate on the first screen. It shows a red, blue and red combination that you put into the mailbox on the left side. Use the coin you get to get a blue flower from the vending machine. That's as far as I got. I'm not into point and click adventure games.
It's mostly because I'm not good at them. I still appreciate the animation. Everything was really clear to understand. I liked the sounds. They were authentic.
