Stack Tower Insanity
Stack. Survive. Fight back.
The stacking game you know — until it isn't. Drop blocks with perfect timing, survive the tower sway past floor 25, and at floor 50 the game transforms: your block becomes a ship, and every floor after that is earned in combat.
Three phases of insanity
Classic stacking, tower sway from floor 25, and full tilt-controlled combat past floor 50.
