ARCHONWARRIORS

It's chess, but capturing doesn't just happen. When you move onto an enemy's square, the two pieces fight it out in an arena built from that square's terrain. Damage carries over between fights. Capture the enemy King to win.

In the arena
WASD move · Space attack · Shift dash. Game controllers work (stick, top button Y attack, left button X run/dash), and on a phone you get an on-screen thumbstick. Each piece has its own weapon, and the bar under your health shows when it's ready again.
Pieces: Pawn a fast foot soldier with a club (or axe) · Knight on horseback, throws his lance or charges you with it · Bishop throws a holy cross that curves back like a boomerang · Rook a castle on wheels with an archer on top · Queen runs and hurls fireballs that burn · King wheels a cannon around, big explosion.
Terrain: Meadow cover · Ice slippery · Swamp slow water · Desert spiky cacti · Volcano lava burns.
