awesome game
very good game my friend. i didnt experience any glitching like everyones been saying. heres a few things i think you should change.
1.) you should make it so once you beat the game you dont have to worry about weight classes. that way the player can have the option of building as many badass tanks as he wants to. that would be hella fun.
2.) this is what happened to me and most likely a lot of players. i would get to the next weight class and fight the heavier tanks, but because my tanks were shittier, i would lose the battle. this was a pain in the ass because you would have to go back to the lower weight classes to make enough money to fight in the higher weight classes. but the thing is you cant go back to the lower weight classes because youve already built your some of your tanks heavier for the higher weight classes. so then u gotta sell all ur good stuff for shitty, lighter things.
thats all i can think of right now. good game though i look forward to playin ur other games.
