Lemmings and The Incredible Machine are combined into this game, with a particular visual aesthetic and a bizarre sense of humour. In Eets, the player controls the game's eponymous character as they go over various platforms searching for puzzle components. To help Eets get where he needs to go, the player must direct a variety of objects into his path. Eets can walk upside down and shoot things out of their spout after sucking them in with the help of whales, explosive mushrooms, and gravity tablets.

Eets made its debut via an online preview in June 2005. The game was initially proposed to publishers as a potential release for the PSP or Nintendo DS but to no effect. On the match, Klei Entertainment worked sporadically for three years and went through various concepts. The game was polished for an extra nine months after it had achieved a stable state.

Gameplay

The character responds to stimuli differently depending on his mood. For example, while fearful Eets won't jump, an enraged Eets can leap across wider chasms. There are numerous ways to change his attitude, such as striking him with chocolate cloud chips, which enrages Eets. Users can download an additional puzzle pack from the official website created by fans and creators in addition to the game's over 100 levels.

The player gains increasingly more lives and consumable powerups the longer they survive. In this way, the robust rhythm, puzzle, and arcade action genres are all represented in the game. In addition, three achievements, unlockable gamer photos, and leaderboard entries are all rewards for playing.
