About This Game

Clear all Stages — ALL AT ONCE.

All At Once is a hardcore 2D platformer where you control tiny golden slimes.

Each stage is simple by itself, but you must control every slime simultaneously.

As you progress, the difficulty ramps up — you'll be controlling more and more slimes at the same time.

The game features a variety of stages, each with unique conditions.

By the end, you might find yourself overwhelmed by the sheer number of slimes you need to control — all at once.
