Customer notes

The season pass also includes the base game, Quantum Conundrum!


Use the Interdimensional Shift Device and switch between 5 unique dimensions to solve brain twisting puzzles to save your uncle.

When you’re dropped off to visit your uncle, you notice something’s wrong. He’s not there to greet you. There was an explosion just as you arrived. And the house seems to be even weirder than you remember. It’s up to you to find—and ultimately rescue—your uncle. Use his newest invention, the Interdimensional Shift Device (or IDS), to switch between five different dimensions and solve puzzles. Switch dimensions in real time, work your way through the crazy complex mansion, and rescue your uncle!

Key Features:

  • Engaging Puzzle Gameplay: Using the Inter–Dimensional Shift Device, players will shift to and from various dimensions to manipulate the world around them.
  • Experience New Dimensions: Each dimension the player gains access to becomes a valuable asset to manipulate objects around the manor. Move between the Normal, Fluffy, Heavy, Slow-Motion and Reverse Gravity Dimensions on the fly.
  • Immersive, Interactive Environment: The look and feel of each dimension is completely distinct. When shifting to the Fluffy Dimension, everything in the room becomes a soft and cuddly version of its previous state.
  • Unique Art Style and Humor: The Professor’s manor and all the items within it have a unique style, but players should also be on the lookout for humorous touches scattered throughout.

Great 3D puzzler

This is a fun little game from one of the members of the Portal team. The game is unique in that you change the physical properties of the world around you (make things heavier or lighter) and use that to solve problems and advance through the mansion of your relative. Later puzzles can be real headscratchers that will leave you immensely satisfied once you've solved them. Recommend this for anybody who enjoys 3D puzzles.


Portal's cousin? ... Maybe

Sebastai | Aug. 15, 2013 | See all Sebastai's reviews »

It's a good game, with a lot of puzzles to solve. You can not compare this game with portal because they are different games, but if you like the subject matter of these puzzle games, it is one of the best games in the genre that you can find on the market at present, I would definitely recommend.


Get it if you like first person puzzles

Portal is obviously the measuring stick for first person puzzles, but be warned that these 2 games are not very similar gameplay wise (despite the similarities in camera view). QC does not have the unique atmosphere or storyline that Portal was so good at. It is generic and cartoony; generally nothing to shout about. However, QC puzzles are arguably as clever as Portal's, and while the consistency of level qualities vary throughout the game, they made up for it in terms of quantity. There's a lot of levels to play here and it rarely gets repetitive. While Portal keeps the gameplay extremely simple (only 2 portals and jump) and let's the puzzle speak for themselves, QC is more complex. You learn new abilities throughout the game, and you need to learn to switch between them at the right time in addition to maneuvering yourself around the level. Therefore be warned, despite its cartoony appearance, i feel that this is a more difficult game than Portal and it's not suitable for young kids. Some later puzzles are very challenging and really push your patience and platforming skills to the limit. I personally enjoyed the challenge but it's definitely something to consider.


DLCs for a platform game

lok0812 | June 21, 2013 | See all lok0812's reviews »

If you enjoyed the base game chances are you will like this as well. One downsize about the season pass is even though it comes with the content DLCs, the DLCs itself are really horribly made. Game style is still the same but this time, no voice over what so ever. You are still doing the timing jump "puzzle" instead of a real puzzle that challenges you to solved, none of that appear in the DLCs. If you are looking for a platforming games then this is it but if you thinking of Portal type games, you might want to look elsewhere since the "puzzles" in the base game and the DLCs are solvable by just looking at them first time, the only challenge is perfect the platform jumps to get to your goal and if you messed up then you get to start all over again.


Portal - it is NOT..

wfosnot | June 3, 2013 | See all wfosnot's reviews »

I bought this game because the creator also created Portal - which is a fantastic game. I had higher hopes for this game. It was cute, but not as funny as Portal. The puzzles were interesting, but the story seemed to lack something. That something that draws you in... and puzzles that you HAVE to solve (stay up all night and figure out) -- didn't feel this way with this game. Maybe after steeping away from Portal for awhile and coming back to this game will make it feel more original and fun. Also, unlike Portal, some of the puzzles were very frustrating because of the game mechanics -- I knew how to solve the puzzle, but got stuck in the mechanics of making it happen.
