Ibb & Obb - Best Friends Forever Double Pack

My honest first reaction to ibb & obb was mild skepticism. Two blob characters, minimalist visuals, a world split by a horizon line where gravity flips upside-down on the other side. It reads as a budget indie experiment. Stick with it for half an hour with the right person beside you, and something clicks. The dual-gravity concept stops being a gimmick and starts being the entire puzzle language, and that shift is genuinely exciting. The core setup is this: ibb (the green one) and obb (the pink one) share a world divided by a thin barrier. Above it, gravity is normal. Below it, gravity pulls upward. Crossing through the barrier carries your momentum with you, so a big falling jump on one side can catapult your partner high on the other. Bounce pads transfer force between players across the divide, and colour-coded gates allow only one character through at a time, forcing brief separations that test your coordination and patience equally. The controls themselves are stripped to movement and jump, full stop. All the complexity lives in the level design, not the input scheme. The game spans 15 main levels and 8 hidden bonus worlds, with a completionist run clocking somewhere between 10 and 12 hours once you factor in secret hunting and the timed leaderboards layered on top. What works is the puzzle escalation. New elements like gravitational bubbles and enemy types are introduced gradually, and the designers resist the urge to pile on entirely new mechanics every few stages. Instead they keep wringing deeper situations from the same core rules, which means every eureka moment feels earned rather than handed to you. Enemies are defeated by touching them from the side where gravity makes them vulnerable, a small rule that generates surprising amounts of tactical back-and-forth between players. The soundtrack, composed by electronic artist Kettel, flows quietly underneath without demanding attention, which is exactly right for a game where most of your mental bandwidth is spent planning two steps ahead. The art style leans minimalist and colourful, with backgrounds and sky gradients that are genuinely nice to look at, even if the character designs for ibb and obb themselves are a bit rough. The honest warning: this is not a solo experience in any meaningful sense. Attempting it alone means controlling both characters with separate analog sticks, which reviewers and players alike have called close to unplayable. There is no AI partner. If you do not have a second person, local or online, this package simply will not work for you. Even in co-op, longer sessions can start to feel repetitive as the visual variety is limited and the pacing is deliberately slow. Some puzzle sections lean into cheap difficulty, obscuring platforms in low light or flipping your orientation at the worst possible moment, which adds frustration without adding satisfaction. Best enjoyed in focused bursts rather than marathon sessions. The Double Pack format exists for one reason: two keys in one purchase, so you and a friend can both own the game and play online without one of you being left out. That framing tells you everything about what the developers intended this to be. It is not a solo purchase dressed up as a two-player option. It is a co-op game sold as a co-op game, and if you approach it that way, it delivers a kind of quiet, communicative puzzle satisfaction that is genuinely hard to find elsewhere on PC.
