Best Friends Forever Double Pack

Get two copies of the game so you can give one to a friend.

Is your ibb looking for an online obb? The Best Friends Forever Double Pack gives you an extra copy of the game at a strong discount. Treat your best Steam friend to a gift and start ibbobbing together online.

Designed for Two Player Co-op

ibb & obb is a cooperative adventure designed for two players. So find a friend for some true co-op puzzle solving fun.

Can I play online?
You can play co-op locally or online. Online you can either invite a Steam friend or match up with a random other player. For a local game you can make use of keyboard and controllers, or a combination of those.

No single player?
Technically you can control both characters simultaneously on your keyboard, but the whole game is really designed around the interaction between two players. On your own it'll be very hard and simply less fun.

I though this game is just funny and easy to beat but I'm wrong.
It turned out to be fun and challenging game.

I ended up finish the game with my friend. Took us 5 hours with repetitive death cause one of us play like a scrub.
Definitely entertaining and will mock my friend over and over again.

I have a hard time reviewing games tbh. This game, however, is a part of a whimsical challenge attributed to the integrity of the friendship with the person you chooce to play it with. I have decided to play with a person I trust in the game world and not just a random ♥♥♥♥♥♥♥♥ that wants to tell me what to do. These challenges, with your friend, are overcome through communcation with a mouse-trail of bubbles (or microphone lol) follow by lots of facedesk slamming, frustration, screen cracking, mouse breaking and blood-curdling, nightmarish bouts of war with the developers indirect laughs in your face. It is a brutal level design for each of the areas and even the smartest people lack common sense, I took a while to write this review because, this friend I chose, we both need breaks and a mutual time to participate in this game. It is well worth it and not only does it build onto the integrity of your friendship, but it creates hatred for self; the realization that one is not always the brightest and when you do finally realize something, how hard it is to communicate it.

Ibb & Obb is a gravity-based puzzle-platformer.

Which isn't to say you manually adjust gravity, as with some games, but that the entire game is composed of things like 'slow fall bubbles', trampolines, looped falling (where you drop from the sky after falling off the bottom of the screen), and reverse-gravity wells.

Despite fairly simple concepts, the puzzles quickly move from charming and cute and simple, to demanding and clever.

Unlike twitch/reflex platformers, once you actually figure out the trick to a puzzle, you're good to move on, which makes this a game more about testing your wit, than your reflexes- though timing is certainly important, as well.

Ibb & Obb is one of the best co-op experiences I've had in a while, and I can certainly recommend it-
Though there's some things I unfortunately have to point out.

* Co-op only play guarantees an experience built with co-op in mind at all facets.

* Puzzles are based around clever reuses of a small set of objects, presented in more and more complex ways, thus creating a steadily progressing experience where you build off what you've learned from your previous successes, rather than having to start each puzzle from scratch.

* Ibb & Obb (the two player-controlled characters in the game) are different sizes. This can have some interesting effects on gameplay, and is actually crucial to later puzzles. It's a nice twist that keeps each co-op partner feeling distinct in their roles. Similarly, the use of color-coded barriers limits which character can progress at points, creating interesting 'how do we both progress' puzzles.

* Looped falling can be surprisingly hilarious

* You can 'bend the system' by attempting crazy mid-air combos, such as trying to jump off your partner as they loop-fall. This can sometimes provide alternative ways to solve puzzles, for players that enjoy precision-reflex approaches over puzzle approaches. But really, it'll take quite a few attempts to do- though it's quite satisfying when you manage it.

* Charming atmosphere, and the most adorable little interactables- that you can actually push into enemies to cause the enemies to change course, or bounce onto enemy killing buttons, or just kick around like soccer balls, sometimes to absolutely hilarious effect. Great little tidbit for more creative puzzle solving, and just general palate cleansing.

* The ability to aim for a perfect score, by gathering all the enemy-kill score drops, for the more dedicated completionists.

* Secret stages are brutal and difficult to intuit, and may be best skipped by all but the most dedicated mental gymnasts.

* This game gets hard. It looks like it's designed for kids, but most kids won't have the patience to complete this kid of game [and if you know one that does, give them a cookie, they're awesome]. This is definitely a game for the patient and the people who really like working through problems until they understand them.
If you're into really puzzle-oriented games, enjoy teamwork, and physics manipulation, you're going to probably like this game. If your expectations run toward something more- or less- active in involvement, you may not.

* Similarly, puzzles will require several attempts to figure out, and at the time we played, all the walkthroughs were for the console version (which has different stages, see Cons below). Plus side, every time we got stuck and needed an assist, it was us overthinking a puzzle, so there's that. :)
Still, patience is a virtue- and one you may need to rely on for this game.
Then again, you'll still die less, hate yourself less, and feel far less frustrated than with twitch/reflex platformers, so there's that~

* Relatively short. 6 to 7 hours without the last level (see Cons), but that's mostly due to repetition in figuring out each puzzle. The core content is probably 2-3 hours in length, assuming a run-through where you know what you're doing.
(Secret levels will of course extend this time a bit further, if you choose to do them.)


* The last level is broken on the PC port- or rather, several levels got reimagined for the PC port (which is kinda cool) but the reimagining of the last level caused it to be incompletable (which is kinda not cool).
The game plays fine up to that point, so if you're able to view the end of the game being a level sooner, you'll be fine-
If you're a completionist, this screw-up may drive you up a wall.
Especially with given how demanding the prior level was- you can only imagine how awesome this final level could have been..

* No mid-level save points. Plus side, once you know the puzzles, you can breeze through if you need to leave and restart- still, this feels like an unfortunate and arbitrary exclusion.

* Likewise, this game seems to have low replay value, given that non-campaign-level challenges (ie, secret levels) are all extreme in challenge, and all puzzles in the game are fairly easy to complete once you know how to do them.

This is a bit of a difficult game to describe, but if you like undertaking a mental challenge with a partner, and neither of you are the type to get agitated when you get stuck, then it's a fantastic game I recommend highly.

As always with co-operation games of this nature, if either person gets easily stressed, expect eventual argument and rage-quitting.
Despite that phrasing, it's not an especially frustrating game (in MY opinion), since everything CAN be figured out through rethinking and continously retesting your approach to a puzzle.

Still, it's a bit niche in its challenge, a bit curious in how certain things (like secret levels) are approached, and, of course, the last level cannot be played.

I tentatively give it a 4/5.

Seriously, if it sounds at all good to you, give it a shot- and if it sounds at all not good to you, don't. ~.^
