You never control just one brother. Press a direction and the whole party steps together, one tile at a time. Walls and obstacles are your best tools: a brother who bumps into a wall stays put while the others keep walking, so you slowly line the party up until every slime stands on the goal of its own color. Undo and restart are always one key away, so trying out ideas is part of the fun.

The road home isn't empty. Bandits and Yetis patrol the boards and move at the same time as you, and not every brother can beat every enemy. Catch a foe from the side or from behind to knock it out, but walk into it head-on and both sides get hurt. Deeper in, one-way portals only open for certain brothers, so picking who goes where is half of every puzzle.
