I really love the creativity and idea behind this, but the gameplay was a bit confusing.
My first goal weight was 2.7 kgs but the closest I was able to get was to get was to put 3kgs on the right side and 0.5kgs on the left side. Then when I added a bunch of feathers feathers I hit the limit which made the game crash/freeze :c
But the idea of a rigidbody scale that you have to try to use to measure the right amount is really good! And the song + nice looking scale were well done!
