Wow, what an amazing accomplishment, this is such a well polished game, the idea is so cool, there's so much creativity and charm. The art is fantastic and the sound and music are great. Definitely one of my favorites of the whole jam, really well done. To think this was made in 72hours is inspiring. I could see this on steam as a fully finished game now.
The difficulty seems a little high early on with how easily the peices are pushed by the others which can get frustrating and tedious, but other than that it's perfect!
