Hack 'n' Stack is a cooperative tower defense game developed by Dodo Tako, a branch of the independent Quebec studio Triple Boris, which was founded in 2016 by Karl Tremblay and Simon Dansereau. The game is the second production by Dodo Tako, which previously worked on Where is Billy?, another party game. The game is available for purchase on the Nintendo Switch eShop for 10.99 euros. In Hack 'n' Stack, players defend a kingdom from an invasion of blob-like monsters. The game requires collecting resources to build defenses and repel enemy waves. While the game can be played solo, it is recommended to have another player for a better experience. Players can choose from a variety of cute animal avatars, such as a shark, a gull, an ornithorhynchus, or a sheep, and can customize their headgear and clothing. The game features a ¾ top-down view environment where players must protect an emitter with three life capsules. Characters can jump, perform ground charges, and use charged attacks, and can use resources to enhance their abilities. Players collect resources such as wood, rocks, and sweets to build stronger walls or turrets to eliminate enemy waves. However, the game's mechanics become more challenging when played solo, and the system is said to be poorly balanced. Critics note that the game's graphics are unimpressive, especially in docked mode, where aliasing is noticeable. The soundtrack is described as forgettable and uninteresting during gameplay, though it is more engaging during character selection. While the game allows online play, it is limited to playing with friends. The physics-based tower defense concept had potential for amusing situations, but the gameplay and enemy variety are seen as lacking in variety. The handling is described as poor, especially when using a single Joy-Con. While the avatars are cute and funny, the overall experience is considered a disappointment.
