About This Game

One small mushroom. One goal: reach the top.

Mushroom Must Go Up is a challenging 3D platformer in which you guide a mushroom with your mouse. Land on a surface and bounce automatically. Choose your next landing spot, adjust your position in midair, and keep climbing.

Simple controls. A demanding climb.

Movement is controlled with the mouse, but crossing narrow platforms and gaps between objects takes precision. Play it safe with a nearby landing, or aim a little higher. The choice is yours.

No checkpoints

A missed landing can cost you hard-earned height. Find your footing wherever you fall and climb again. Need a break? You can quit and return later: your current position is saved so you can continue your attempt.

3,520 metres across 22 themes

Climb through a rusty factory, a toybox, and a giant’s table on your way to spaces high above the ground. New scenery and a variety of objects await as you gain altitude.
