Incredible little throwback to the RTS's of my childhood. You've nailed everything from the look to the sounds of those games.
My only complaint is that if you encounter a stronger mech, you can't run away from it, as it'll chase you to the ends of the earth, which can be a death sentence early on. I also had a bug after one of my mechs lost an arm, I couldn't repair it at the repair bay, and it could no longer attack, despite still having a weapon on its other arm. Enemy mechs would also just ignore it like it didn't exist.
Still think this is an amazing game though, as I've been coming back to it again and again since I downloaded it early today. I'd actually quite like to see this expanded further, we need more RTS games out there!
