QuantAttack by ytakamiya is a match-2 type action puzzle game made for PICO-8.
In this game, blocks are cleared by lining up two blocks of the same type vertically. It introduces a fresh twist to block-clearing puzzlers. Some blocks are unique, and you must discover hidden patterns to clear them. There are more than 40 patterns of such block combinations, and finding and mastering them is the fastest way to improve. These secret patterns are based on the rules of quantum mechanics: each block is a quantum computer instruction, which works exactly like an actual quantum computer instruction.
