Locking glitch
I don't know if everyone is experiencing this, but I did when I tried this game out. Whenever there was a big battle with lots of enemies around (Especially the part in the first level with the huge artillery cannon that does tons of damage) ALL of my weapons lock up on me and will not aim, they'll still fire, but at nothing because they only fire straight ahead where enemies usually don't reside. Due to this I have never gotten past the first level, no matter what weapon or wagon combinations I tried. Because of this I rated this game overall a 4, because though it is a great game other than that glitch, (I hope it's a glitch) the glitch ruins the game completely.
