Yep, I wish I could have add some visuals, but even before the jam started I knew I wouldn't have enough time for that. Especially since I'm not particularly an artist, and I have still never programmed dynamic drawing. However I had planned some ideas, with a landscape that would change with shapes added and removed with instruments. A bit like what Google did for its Oskar Foschinger doodle. I don't think I will implement the idea in this game (I like keeping game jam as close as their original form), but I definitely will try to do it in a next game!
Thanks for the feedback!
