Really happy to hear you enjoyed it, and thanks alot for the detailed feedback and kind words. Regarding the engineering graph paper notebook, I actually experimented with lined and blocked paper as a background but just could not get the same game feel with those backgrounds. I get your point however, there is probably a middle way. Maybe a key that allows you see your previous drawing (with lower opacity) in the drawbox, so you can draw over it? As for the key to draw straight lines, thats a great idea!! I am planning on developing a well-rounded remake at some point, maybe you'll get to play it someday:) Cheers!
