TumbleSeed is an indie action video game, created by developer Benedict Fritz and designer Greg Wohlwend, in which the player balances a rolling seed on an ascending, horizontally slanted vine past procedurally generated obstacles to reach the top of a mountain. It is based on the mechanical arcade game Ice Cold Beer and built partially through the Cards Against Humanity game incubation program. TumbleSeed was released in May 2017 to generally favorable reviews on macOS, Nintendo Switch, PlayStation 4, and Windows platforms. Critics, in particular, appreciated their haptic sense of the rolling seed from the Nintendo Switch’s sensitive HD Rumble.
