This is an interesting twist on a very old concept. Still, I must say I liked the old one better, as in this one speed seems more important than correctness (clearing as many as you can).
When you want to put a shape back to the menu, you have to click on the exact spot. That doesn't help when you're running out of time and playing fast. You should be able to put a shape away by clicking anywhere on the menu.
This one's a lot of fun! My only complaint about your games is that it takes long to figure out how things are supposed to work. Gamers usually don't have that patience. Please consider introducing tutorials. I give this game 5 stars.
OMG, this looks so much like my VLSI design class that I don't even want to play the first level :D (even though I'm curious as to what all this has to do with communism)
This game reminds me too much of industrial informatics to be fun... however, the premise as well as the levels are well thought-out. 5 stars for an impressively good puzzler (even though I only played the first two levels ^_^).
