Man it's just incredible that people can make something so clean in only 4 days. It all looked so good I honestly would love just a sandbox mode where I can (at least act like I) become a true artist.
Music, gameplay, teaching of mechanics all great. One of my favourites so far for sure, and this type of game isn't one I usually enjoy (I find management of resources can be tiring for me, but I never felt that here). I hope you continue development after the jam. A little more depth and variation is all that's really needed to fully release!
