Pizza Tower is a 2023 platform game created by the indie developer Tour De Pizza. It follows the pizza chef Peppino Spaghetti, who must scale a tower to prevent the destruction of his pizzeria. Across 20 side-scrolling levels, the player increases their score by gathering collectibles and defeating enemies to build combos. At the end of each level, they activate an escape sequence and must return to the beginning within a time limit. Pizza Tower does not use health or lives, and its difficulty depends on what the player chooses to achieve.

The five-year development was led by the pseudonymous designer McPig and programmer Sertif. Pizza Tower began as a role-playing video game with survival horror elements before evolving into a platformer inspired by Nintendo's dormant Wario Land series, to which McPig wanted to provide a spiritual successor. It was developed with GameMaker and features a cartoonish, high-resolution pixel art style inspired by SpongeBob SquarePants and French comics. Wario Land 4 (2001) served as the basis for the gameplay and level design.

Pizza Tower developed a large fandom during its development through early access builds offered to Patreon backers and game demos. It was released for Windows on January 26, 2023. Pizza Tower received positive reviews and nominations for year-end accolades. Critics praised its gameplay, music, visuals, and humor. Critics favorably compared its art style to 1990s Nicktoons and the sense of speed to the Sonic the Hedgehog series. They considered it a worthy substitute for Wario Land, some calling it better than its inspiration. Tour De Pizza supported the game with updates adding new content into 2024, alongside a port for the Nintendo Switch.

Pizza Tower is a side-scrolling platform game. Its story begins when Peppino Spaghetti, an Italian pizza chef and the owner of a struggling pizzeria, is approached by Pizzaface, a sentient floating pizza. Pizzaface threatens to destroy Peppino's pizzeria with a nuclear laser atop a nearby tower. Frightened and angered, Peppino sets out to ascend the tower and defeat Pizzaface to save his pizzeria. The tower serves as the setting and hub world of the single-player game. It has five floors, each containing four levels and a boss. Each level has a distinct theme and unique game mechanics, such as a cemetery with surfable corpses and a Five Nights at Freddy's homage with jump scares.

Peppino, the primary player character, can walk, run, jump, roll, and slide. His attacks include a body slam, grabbing and throwing enemies, and a parry. If Peppino runs for long enough, he begins to dash, allowing him to run up walls and plow through enemies and objects. Defeating an enemy initiates a combo that lasts seven seconds; to maintain it, the player must defeat more enemies and collect items. Certain levels feature power-ups that alter Peppino's abilities, such as guns or knight armor, and Gustavo, an alternate player character who rides on the back of his giant pet rat named Brick. Palette-swap outfits for Peppino can be acquired through completing challenges and obtaining achievements.

Each level contains various secrets: pizza topping creatures that the player rescues to unlock boss fights; a treasure locked behind a door that can only be opened by a janitor the player must find; and three hidden rooms that provide points. At the end of most levels, the player finds a pillar they must destroy. This activates "Pizza Time", a phase in which the player must return to the level's entrance within a time limit to avoid being caught by Pizzaface. The player is forced to restart the level if they fail. A portal allows the player to do an optional second lap in which they return to the end and must make their way back to the entrance again for bonus points. After completing each level, the player is given a letter grade based on their score and performance. The highest rank, P, can only be acquired if the player obtains enough points, finds the three secrets, collects the treasure, and completes a second lap while maintaining a single, uninterrupted combo.

Pizza Tower does not feature traditional difficulty levels; rather, the difficulty depends on what the player chooses to achieve. Secrets are optional and there are no lives or health. Colliding with an obstacle does not hurt Peppino, though it lowers the player's score and subtracts two seconds from the combo timer. The only stages where Peppino can be harmed are the boss fights, arena battles against foes such as Pepperman, a large anthropomorphic bell pepper; the Vigilante, a cheese cowboy; and the Noise, a TV star and Peppino's archenemy. The player must dodge the bosses' attacks and deplete their health to proceed. A New Game Plus mode featuring the Noise as a playable character was added in a free update on March 12, 2024. The Noise controls similarly to Peppino, but has a slightly different moveset revolving around his skateboard and jet pack. Playing as the Noise also alters the user interface elements and music.

After completing the game as the Noise, the player can uncover an Easter egg that unlocks Swap Mode, a multiplayer mode that allows two players to compete for the most points as Peppino and the Noise. The first player starts with full control while the second player follows. To switch control between players, the first player must get hit, get grabbed by the second player, or willingly allow the second player to take control.
