Mask Valley

Mask Valley is a gripping rogue-like card game where every breath counts in a poisoned world of toxic haze and crumbling valleys. As the last hope for survivors across 10 fragile tiles, you're dealt 5 cards each round—masks, filters, barriers—to place strategically, protecting populations from creeping contamination, shifting winds, and rising threats. Play every card, resolve their tense effects, then draw a chaos card you choose: a lifesaving rain or a devastating collapse that can wipe out zones forever. No two runs are the same, with placement puzzles, massive swings, and escalating dangers testing your every decision—one wrong mask, and the valley falls silent. Download now and see how many faces you can save before the haze claims them all.
