It seems a bit bugged on level 3, can't add up to 11 even though I got 5,4,2 on the scale. The art style is amazing! This needs much more recognition!
i assume you put them on the scale, you have to actually be holding the weights unfortunately. i have it calculate ones that were sitting on it but didn't have enough time to, sorry if that was a bit confusing, and thank you for your kind words!!
