So good! Reminded me of tricky towers, but with its own twist. Great entry and solid level design. 

If you add some music and/or sound effects the game is perfect for a nice and chill game. Also I'd add a little hint like "you need to build this high" in the first levels, just so people have a better understanding of what to do.

Fun game! Really good physics!

Great job! Was a fun game with pretty simple objectives.

Nice game! Simple game yet very effective. 

it was fun, each level was harder than the past one.

Fun game. The available shapes make for interesting combinations and as they balance and rotate, it gives off that fun kind of worry when you let go of a piece, hoping the tower will hold.

Fun concept, the scaling in difficulty was also nicely done.

Nice little game. The last one was tricky!
