Huge fan of the style you're going for with this. Definitely feels like something I'd play during the MS-DOS days. The art style is extremely minimalist but, is able to depict everything so well! (also that main theme is very catchy)
One suggestion I'd make for a game like this is time controls like pause, play and fast forward just for situations where its a couple archers facing their inevitable doom against a giant army and you can kinda guess the outcome already.
Amazing job with this though, I really enjoyed it!
