excelent game. only the challenges are very difficult, we should be able to at least unlock next challenge without being perfect, so you don't have to play it over and over. is very frustrating
great game! i don't quite get how that overcharge thing works though.. it seems to rest attack points, but maybe it would be better if it adds to attack points. also, this really some kind of upgrade system
too hard, from stage 8 you have to replay a millon times each stage and gets boring. needs balance. also the upgrades don't seem to make any difference
