ibb & obb

ibb & obb is built around two-player co-op and the small but sharp trick of moving between upside-down gravity zones. By our assessment, that simple rule is its best feature, because it turns every jump into a tiny shared puzzle and makes communication matter more than speed. The trade-off is that it has very little interest in being forgiving or sprawling; without a partner who likes coordination, the whole thing loses most of its charm. In practice it is all timing, slopes, and the odd moment where one player holds a line while the other drops through a different layer of the stage. Compared with bigger puzzle-platformers, it is stripped down and narrow, but that is also why its ideas land cleanly. The game is at its best when two people are sitting close enough to talk over each jump, and the levels are built exactly for that kind of attention.
