This game is quite entertaining, but its main gameplay feature, the "unlocking" of new mechanics can sometimes be a little bit like Pixel Quest, which used in game money to purchase game mechanics (like DLC), or this PSP game called "Z.H.P. Unlosing Ranger VS Darkdeath Evilman" One boss battle evolves throughout the game, and visually changes. I really like the idea that the combat changes, and have been enjoying the novelty of this game
