The game is extremely difficult like extremely difficult. Every enemy has AOE skills and can teleport. You can't dodge effectively, ever. The developers know that the game is hard so they allow you to turn off enemy health regeneration and allow you to max out your own health regeneration. This only makes the game a little bit easier.

The English translations aren't the best, but you can definitely follow the storyline and jokes. The storyline is funny so if you have $6 and time, I would recommend. Remember the game is not easy.

I always want to mention that the mechanics aren't really gone over within the game. (There is no game tutorial.) I had to read the end of store page description to find out that "z" starts battles.
