I wound up putting a fair bit of time into Quantum Conundrum today, almost completing one of the three wings, so it’s not going to be a terribly long game.

It’s common to compare it to Portal, as it’s the same kind of solve-a-puzzle-as-you-go-room-to-room, but with dimension shifting instead of portals.  One dimension makes things lighter, another one makes things heavier (and there are two others I hadn’t reached yet), and you might need to put items on a pressure plate and block a laser but you have to be careful about the order you do things in because the laser will destroy the item in the regular and light dimensions but you have to shift to the light one to move another item that would normally be too heavy, and fans will blow around items that are too light, etc.

The puzzles that require some thought are fairly interesting, but unfortunately there are some segments where you have to position items and then jump across on them, and the jump mechanics aren’t so good, making those segments a bit frustrating.  Overall though, I think it’s still good enough to come back and finish off at some point.
