Was not expecting to see any RTS games pop up, what a treat. Excellent use of the limitation; all the art and animations look perfectly retro.
Amassing an army is fun, but I found the camera to be painfully slow. It may be a bug on my end, but I could easily walk out of the bounds and get lost, and dragging the mouse nudged the camera around a few pixels, if at all.
Otherwise, very clever and well done. Good luck in the Jam :D
