I like the freeze/unfreeze mechanic. It's simple, but leads to interesting gameplay. You've got a nice concept here.

I struggled with the controls a bit, but it's interesting!

Neat mechanic and concept, I'd like to see it once you've fleshed it out some more. This version could use some polish.

Oh, and I managed to get it stuck on level 2 by throwing the box when flush against the wall: http://imgur.com/ZduznQc

@Jaus_LXXIV Whoops, that wasn't suppose to happen.
Thanks for the bug report, I know exactly whats causing that.

Nice mechanic, it's a great concept. Good gameplay too, if perhaps a little laggy.

Z and X is always a bit hard for us QWERTZ'ies ;-)

As in the previous comments: The concept is great. I can see brain racking levels around that :)

Ahh, this game makes me feel like a moron. I feel like I SHOULD know what I'm meant to be doing, but I don't. Which is actually a really good thing, since it's making my brain work.

Good job!

A little tricky but the idea is great, well done! :)

Nice game idea, a little buggy but not bad.

Cool game concept! I made it to the end after being confused for a while because the controls were a bit difficult to grok, I think simplifying them would help greatly. Here's what I'd do...

Get rid of the Z/X select block buttons. Make it so the last block the player held is the selected block. Make the selected block much more obvious like totally change color, there is only a very thin outline. Put the phase shift button on spacebar and/or z instead of down so it isn't confused with movement controls. Make it so a block changes color when it phase shifts, you need to better communicate to the player what's going. After the player has finished a few levels you can introduce more gampeplay concepts like the ability to change which block is selected instead of starting them off with that ability. Generally it works best to start the player out with the minimal tools necessary and spoon feed them new abilities as they progress.

@KilledByAPixel Yeah, I ran out of time before realizing how confusing it can be. Thanks for the suggestions, they make more sense.

Cool concept.

Nice adea with the physics!

Very nice mechanics, I wish the movement was a little smoother though!

Good concept

Really clever idea, you could probably do quite a few more levels with it. I like the double-jumping, though the jumping in general feels a bit floaty.

Good idea for a game

Nice game. The concept is really awesome but the controls are a bit confuzing
