This is a great concept! The pencil and paper style to the game is neat and lends itself well to an RTS game. I definitely felt that child-like quality/theming of the game. Reminded me something along the lines of an annoying little brother screwing up a drawing I was working hard on, only to outsmart him with my imagination.
It did feel a little difficult to control the units at times, but perhaps it could be my own fault. Perhaps if the units were a bit bigger, it might help to alleviate this issue. I'd love to see this concept expanded further! I made a video with my gameplay and commentary, keep up the great work, it was a fun time!
