Good concept. maybe change the circles into a structure that has more flat areas like a hexagon.

couldn't break 10. really about the luck of the draw. had lots of triangles and circles to build at the base each time i hit 10

this is fun, could introduce different materials so they can vary on weight/stickiness. good stuff!

Nice game but it could use some sounds and personally I would like to see what is in my hand instead of in the left corner of the screen.

Nice. The only improvement I can think of (other than the two that are listed) is to show the next three or four shapes that will come instead of just one, to make it more of a puzzle game and less luck-based.

Really nice idea, and the different shapes make a good puzzle, the only thing I think you can improve is adding some music / sound effects.

Here is my best at the moment, will try more again tonight :)
