A LOT of improvement is needed...
The robots are killed in one swing, the bosses are simply 'dodge and slash,' with no strategy needed, and the storyline is complete crap. You need to slap a lot of improvement into this mother, otherwise it isn't deserving of its front page title. Make more robots than the "roll around while you kill me" and "walk in an easily avoidable line while swinging my arms" type, and put weak points on the bosses, so you have to think where to slash them at to kill them. Also, work on the storyline, because I've seen honestly no more of a loose plot than in this. Anyway, that is all.
