The mechanics and mech feel are so tight and responsive it really fills me with joy! I really like the rough like nature of going from level to level, gathering resources, at the beginning I thought the exraction point was annoying but later I began to like it, Although it might be easier if there is a big red marker or something pointing to it, and this game with just a bit more sound effects and a pretty coat of paint over the menu and such, I tell you this would be easily a top contender!
Already as it is, is a great prototype! If you kept working at it, this could become something more!
