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.
