Cool game, but I didn't see how the jam's limitation is used, maybe I'm just dumb. And the gameplay is pretty routine. I admire that you drew on paper and then scanned it, and it looks really beautiful. I'll definitely try doing something similar in the future!!
I definitely recommend giving it a go! It was quite challenging to make it seamless for the scrolling to work I had to draw it in two halves on separate sheets then keep swapping them over so that their edges always matched. But I think it was worth it for the unique look it gave. :)
