A lone warrior fighting in his mech in a galactic tournament! Pride of humanity is at stake! This kind of setting is what games were made for! I'm pumped just thinking about it!
But there are two fights in the game, so that means it's the semi-final and final of the tournament?
I like that you have a ranged and melee option. Also getting hit lowers your mechs performance - that's a nice touch.
Anyway, nice job!
