"Chirality is a one-switch game of reflexes and perception. Watch for matches among the symbols as they rotate left and right, all the while getting faster as your score climbs higher. Three different difficulty levels allow you to play at your own pace, but the challenge is everpresent".
I like this game - it's simple, but has a compulsive hectic nature, much improved by a very fine sound track. This isn't the finished version, with some accessibility tweaks to be added (hopefully).
