5/5 ★ – MattGoode's review of Öooo.

it's short but i can not think of one aspect about this game that was not excellent. the puzzles are incredibly genius. the structure of the game is so cool. it is, at its heart, mostly a knowledge metroidvania, but it is presented in such a unique way. this game should be studied in game design courses for how clever it is in laying out its puzzles and teaching its mechanics.
