Great puzzle game :)

I played this, and really liked it. It's nice and quite polished.

Graphics 5/6 : The graphics were nice overall but there were a few things I didn't like: the bricks look a bit weird when they're idle, and I'd suggest using alpha masks to make them look smoother. Then there's the options menu. The font is a bit hard to read.

Sound 5/6: The music is great. The effects are also good. A 'THUD' noise would be nice when a block falls on the ground.

Gameplay 4/6: The game is really original. Not my type of game, but a great game nevertheless. The physics are impressive, and the level design, clever, with all sorts of challenges. I encountered a bug, however. In the windy level, i finished the building, but right before I passed to the next level, the wind tore it down, so I was stuck in that level. (i couldn't create any more blocks, even though I had several of them still available). The tutorial is also good, but it should also explain how to unlock more levels, and how to get more points. (better time, fewer blocks)

Story 4/6: The story is good, and there's also an intro which can be comfortably skipped.

Interface 5/6: The interface was really neat. I liked the custom message boxes, but it seems that on some point you still used the show_message function because I could see the windows cursor when I had to click OK. But this is a minor issue. Also, the options menu doesn't show the options. xD It shows the highscores and help. You should change that. Make a 'Help' and a 'Highscores' button, and in the options menu show stuff like music:on, fullscreen:on, etc. , rather than just saying press F9 to take a screenshot and so on.

Overall 4/6: A cool game! Original. Almost completely bug-free and nicely made. Well done!
