Quick note: The below solution is obviously for Lvl 34. And the circles are still placed in pyramid form. There should be enough of an angle with the grey piece that the others don't slide out from under the top circle.
Everyone is having a problem with rocking... Why not stop the rocking? Grey piece down long ways, a little more hanging on the right. Rotate the green so that the short side is down, thus propping up the grey at a slight angle. Cross piece on the top of the grey, left side. Then the three circles. The circles will settle against the cross piece, no rocking. Done.
Just for kicks, I looked at your other games. Dude, you should be banned from uploading any more crap. Its fine if you are learning, but don't bother us with your failed attempts at creativity. Idiot.
Why would you give a 5 rating on such a complete waste of time? There is no skill, no adventure, not even any puzzle. The is a "how to" if someone has never used a point and click mouse before.
