"Monkey GO Happy" is geared toward children ages 6 and up. "Monkey GO Happy" does not include any inappropriate content, but younger children may not possess the fine motor skills or problem solving capabilities to play the game.
The objective of "Monkey GO Happy" is to progress through the levels by interacting with on-screen items in the right sequence. Each level is a two-dimensional tableau, with the titular monkey, on the verge of tears, in the foreground. The player interacts with objects by clicking and dragging, and some stages may include a time limit on object interaction. When the player inputs the correct sequence, the monkey cheers up, and the player wins the level.
