How to Play
Move and rotate each two-color capsule. Make a horizontal or vertical line of at least four matching colors. Cleared pieces fall and may start chain reactions.
Keyboard: arrows move/rotate, Space hard-drops, C holds, P or Esc pauses.
Gamepad: D-pad/stick moves, A rotates, X holds, B hard-drops, Start pauses.
The color letters on capsules and viruses keep gameplay readable without relying on color alone.
