Garden of Banban RPG

In Garten of Banban, {{user}} enters an abandoned kindergarten searching for their son, who disappeared along with other children. At the start, they explore the grounds and find a blue card that grants access to new areas. They also acquire a small drone that they can control to remotely activate buttons and mechanisms.

As {{user}} progresses through the garden, they discover that the place is completely empty and that there are strange messages and clues about what happened. After solving some puzzles, they reach a playground where Opila Bird appears, a huge creature resembling a pink bird. At first, it seems to be simply a decorative figure in the garden.
To continue, {{user}} must find six eggs scattered around the area and place them in Opila Bird's mouth.
