Casual The UnderGarden will immerse you in labyrinths of underwater caves that are teeming with mysterious life forms, as well as hundreds of hidden secrets. The action game is made in 2.5D graphics, and local locations are filled with luminescent vegetation, which reacts to the approach of a mysterious animal – the local protagonist. The entire gameplay of the game is tied to the interaction of the character with the outside world, who lives his own life and reacts to the actions of the creature.

The adventure can be completed alone or organized in pairs. To overcome the intricate levels in The UnderGarden, you need to complete a variety of puzzles based on local physics. The character's task is to find all the members of his musical group in this underwater world and bring them to the surface. You can make friends with some strange life forms and then they will help in the search, while the other part of the living creatures tries in every possible way to harm the hero.

Physics based puzzles can be solved by placing fruits. They need to be positioned in such a way as to weigh down the lever or raise the platform. This allows you to get into a previously inaccessible area. To overcome environmental puzzles, you need to grow various exotic plants around the hero. Nature reflects on it with bright bursts of light and music. The game has 20 levels, each with its own color scheme and unique vegetation.
