Echo Step

Reach the gate. The ground has other plans.

Every white block you step off collapses behind you. Gold holds forever. Step off a red block and every red block on the board goes with it. And you may never stand still - a direction with no footing is simply refused, so the turn does not pass and the board waits.

Then there is the echo. It copies your direction but not your obligation: it moves the same way you do if there is ground for it, and stays exactly where it is if there is not. It breaks blocks under itself the way you do. It cannot share your square, and you cannot walk through it.

That last rule is the whole game. You can strand your own echo somewhere it cannot reach - sometimes by accident, and sometimes because stranding it is the only way through.

FOUR CHARACTERS, TWO HUNDRED STAGES

Alien, robot, ghost and angel each walk fifty stages of their own, opening on a board shape of its own. They share one rule set; what differs is the mix of pieces the boards are built from and the order the rules arrive in. All four are unlocked from the start.

EVERY STAGE IS SOLVABLE, AND THAT IS CHECKED

All two hundred boards were generated and then certified by two independent implementations of the rules that have to agree line for line - including the exact shortest route. Nothing here was placed by hand and hoped for.

NO ART ASSETS

Every block, character and crystal is drawn from primitives at runtime, in isometric projection, with a palette per character.
