This is unironically a wonderful game. I wouldn't change a thing about it except for maybe having the "march like a good soldier" be a little more intuitive. The hand-drawn graphics actually benefitted this game and I got a big kick out of the "click anywhere" at the very beginning.
One other critique would be maybe some kind of ambient music? But I'm not even sure an experience like this needs that.
Kudos, friend! Amazing product.
