TumbleSeed

TumbleSeed begins in a quiet forest village disturbed by angry creatures creating holes in the ground. A seed is tasked to fulfill a vague prophecy by ascending the mountain, progressing through the forest, jungle, desert, and snow, to save the town. The player controls an ascending, horizontal, and slanted vine to balance a rolling seed past procedurally generated holes and enemy obstacles to reach the top of a mountain. With a controller, the player uses two analog sticks to raise and lower the two edges of the horizontal vine while managing the momentum of the seed.

If the seed falls into a hole or hits an enemy, the player loses a life ("heart") and resumes from an earlier position, but the game ends once the player runs out of hearts. Some punishments are more severe: A seed that falls into a hole will resume from the last flagged checkpoint, but if the seed collides with spikes or loses all hearts, the game ends and the player returns to the bottom of the mountain to try again.

The game is based on Ice Cold Beer, a mechanical arcade game in which the player controls the ends of a metal rod to raise a rolling, metal ball vertically in a wooden cabinet while avoiding holes cut into the wood. The Chicago-based indie development team found the machine at an arcade where they competitively played the 2013 video game Killer Queen. Developer Benedict Fritz later prototyped a version of Ice Cold Beer in the Unity game engine with a simple white background and black, circular holes. His friend, designer Greg Wohlwend, who had previously worked on Threes and Ridiculous Fishing, saw a short, online video of Fritz's prototype and the two began to work together on the project by adding enemies, an in-game world, and procedurally generated levels.

Their prototypes included dungeon crawl and open world, action-adventure genre explorations. They spent two years designing the title and wanted to honor and contribute to the legacy of Ice Cold Beer. They also worked through a Cards Against Humanity game incubation program in 2015, and several other indie developers based in Chicago joined the production: David Laskey, Jenna Blazevich, and composer Joel Corelitz. Based on the project's loose, collaboratory nature, Metro called the game's pedigree "as indie as indie gaming gets".

The game received "generally favorable" reviews, according to video game review aggregator platform Metacritic. Reviewers recommended the game, in particular, for short bursts of play with the portable Nintendo Switch. Reviewers considered the Nintendo Switch's HD Rumble a good fit for the game's core rolling mechanic and aesthetics. Nintendo Life said HD Rumble made the Switch's portable mode "the definitive way to play" TumbleSeed.

Its haptic sensation approximated how it felt to play the mechanical Ice Cold Beer. Reviewers additionally compared the Ice Cold Beer conceit to the core mechanic of Shrek n' Roll (2007) and portable, plastic maze puzzles.
