Circa infinity is a game where form follows function and function follows form. If the image of a bold circle on the screen was the chicken, then the mechanic of a wrap-around platformer was the egg. The constant trickery of its concentrated concentricity is confoundingly circular, but once you’ve bought into the premise, it makes perfect sense. Player-friendly level design and a well judged difficulty curve let the fluid intricacy and fiendish challenge shine, while its distinctive appearance will leave an indelible mark on your mind.
