Every ps1 classic on the PSN store that is available in all regions should be on the Vita by now. Sony should be ashamed for not working harder to make this happen.
Such a cool tower crawler I think every one love it perhaps ^o^ . Also to further push the idea of making this game tower and dungeon crawlers has pretty much always caught people's eye, What's better than finding monsters and taming them as well as finding new ones to control. As well as going up up up to find more neat swords and shields and be caught in that oh crap need to leave with all my treasure and not lose it.
