Great game mechanic. One of the best ideas I've come across

Really nice mechanic!

It was fun figuring out and finally pulling off the bounce to the higher platform on the second level. Unfortunately the third proved too frustrating. Could the shapes be made a little more stable without spoiling the game?

Very nice idea! I really like the gameplay mechanics. The physics are a bit weird sometimes, but overall a cool game.

I had fun figuring out a way to beat the game. It was tricky, but not too frustraiting. It's a fun mechanic.

Really nice mechanic but the controls are a bit too much hard to be just mouse, you could use like the arrows to quickly extend the piece.

But all and all this is a very good game, keep working at it. :)

Very nice puzzle concept!
That would be nice to have a counter indicating how many cubes you can still extend, as sometimes it fails to extend without reaching the limit (probably because of the position/rotation).

i like this particular puzzle idea. with more work this could be a great game.

Oh no! Can't beat the second level, try as I might. Great game, really good idea and well executed. The presentation and sound feels Nintendo-esque. Only problem is the difficulty level, in part due to mouse accuracy (tricky to touch the hotzones when your blocks are moving) but also brutally low margins of error for the early levels. A "weird" game like this should have at least 3-4 very simple levels to let you get comfortable with the mechanics.

Really though, the best improvement would be to have the end blocks be more forgiving snap points, and once you click one of them you are in "erase mode" where you can go pretty far off with the cursor and still remove blocks. Similarly if you start near a "grow point" it will let you extend easily without having to touch exactly on every successive square. That way it should be easier to quickly "move" in mid-air by growing and shrinking as appropriate.

Great job though!

Didn't understand how to pass the second level, but certainly good game mechanic. :)
