ibb & obb Gravity Is Optional, Teamwork Isn't

A cute two-player platformer where one of you stands on the floor and the other on the ceiling, and every jump only works if you time it together.

ibb & obb is worth it if…

  • you have one friend or partner to play with and want a game built for exactly two

Gravity with a split personality

The whole game hangs on one idea: gravity goes both ways. You and your partner travel through the same space but on opposite sides, one falling up while the other falls down, and portals flip you between the two. A jump that looks like a leap of faith is really a landing, once you trust the other side of the screen. You use each other as platforms too: one player stands still, the other bounces off their head to reach a ledge neither could reach alone. It takes a few minutes to stop thinking in single gravity, and that moment of rewiring your brain is where the fun starts.

Puzzles that need two brains

This is a game built for exactly two people, and every puzzle assumes it. You talk things through, try a plan, watch it fail in a new and interesting way, and try again. The solutions are rarely complicated, which makes it funnier when you both stand around for ten minutes doing the wrong thing perfectly. Later levels add new mechanics on top of the double gravity, so the thinking keeps changing. Checkpoints are frequent, so a failed attempt costs you seconds, not progress. The difficulty comes from coordinating and executing together, not from memorizing patterns.

Hidden worlds and shiny things

Beyond the fifteen main levels there are eight hidden worlds, and finding them is its own puzzle. They push the double-gravity tricks much harder than the main path, so treat them as a challenge for after you and your partner have found your rhythm. Levels also hold collectibles to gather, and you can replay any level to sweep up what you missed. Some of those collectibles demand tight timing and a bit of luck, so perfectionists should know the full sweep is the hardest part of the game. The main story through is a much gentler ride.

Made for the couch

This is true local co-op: two controllers, one screen, one friend within shouting distance. The mood fits it well, casual sessions that are social and shared, with plenty of laughing at each other's mistakes. The look helps too: bright, hand-drawn art with soft rounded characters, and a warm melodic soundtrack by Kettel that gives every level its own music. It is a relaxed game to spend twenty minutes in on a weeknight, or a few longer evenings with a partner or friend. One honest note: online play can be laggy for some pairs, so the couch is the surest seat.

Is this game for you?

Can you play it alone?

The game is designed as a strictly two-player experience, with no single-player mode. It works best with one person beside you on the couch, and online co-op is there if your partner is elsewhere. There is no way to fill the second seat yourself.

How long does it take to finish?

A relaxed pace through the fifteen main levels fits into a handful of short sessions, and some pairs finish in well under ten hours. The eight hidden worlds and full collectible runs stretch that out considerably, since they are noticeably harder than the main path.

How hard is it, really?

The main levels are a moderate challenge: puzzles that need real thought and some precise jumps, softened by frequent checkpoints so dying costs little. The hidden worlds are where the difficulty lives, testing the double-gravity skills to the limit. Two patient players who like thinking out loud will get through the story without a guide.

Do we need to play on the same couch?

No, there is online co-op as well as local play. Fair warning from long sessions online: the connection can be laggy for some pairs, which matters in the trickier levels. If you can sit next to your partner, that is the smoothest way to play.
