I echo the comments before me: really solid 1v1 shooter. The ace is not a willy-nilly title after all XD
I liked the map, really gives you proportions on how big the mechs actually are.
The sounds are a little too loud, and once the Ace spots you, it is pretty much game over. At least for me. A minimap of some sorts would've helped a lot. Reloading takes ages for me, but the ace seems to reload in no time. Time to go back to mech school to learn how to do it better I guess :D
A solid foundation. Good luck on further development of your game!
