Haunted Grove is a 2D cartoon-style casual game available on Android that blends tower defense and strategy elements with item synthesis mechanics. Players assume the role of forest guards tasked with defending a door against waves of enemies. The gameplay involves drawing props and strategically placing them in designated areas to create both offensive and defensive setups. While all characters share similar abilities, their unique appearances add a visual flair to the game.

The main interface allows players to start the game easily and find rooms to rest. Players can collect items by clicking on a trash can, and by dragging and dropping these items, they can build defenses or combine them to create more powerful versions. The objective is to eliminate enemies and protect the room; failure to do so results in losing the game. This combination of mechanics offers a fresh take on the strategy genre.
