It's a good first game, but there's quite a few problems. The game's start is quite confusing, and you're essentially thrown into battle before figuring out how to learn the differences between the 5 characters and their various skills. The "opponent attacks whenever" rule also discourages the player getting immersed in the game with so many actions happening and no time to think. The game also isn't letting me save and isn't telling me why, despite having cookies enabled and being connected to the internet.
HOWEVER, once you look past those aspects, the game seems to get better. But I don't know, though - the game won't let me save, so I have no motivation to continue past level 2.
