This game really embodied the "unstable" theme! I enjoyed the art and sound; the little faces on the blocks and noises when they dropped gave them a lot of personality. For extra challenge, you could maybe consider adding obstacles or preset objects onto the stage before the level starts. Nice job!

Really funny game! It is harder than Tricky Towers with some pieces that are complicated to use in the construction! The graphics and the sound design are great, well done!
