That marketplace sprite sure is bustling!
The fact that I have to redraw the entire path every time I need to erase something (and thus can't easily iterate slightly improved designs during some stages) made it a bit too frustrating for me too finish, but that's partly a "me" problem. The game is well made with enough features and content to be an enjoyable way to spend some time. Good job!
Also this guy 
is so frustrating!
