This game does have a few good aspects to it, like turn based fighting, which I greatly miss in many of today's hack'em slash'em active time battle systems.
I did not mind having to share HPs and MPs between the two characters as you start off with a decent amount of both.
The game play is easy to pick up on and not difficult to master. The only drawback to the game is that you have to share CPs between both characters in order to attack "monsters". Sharing CPs can make the game more difficult as you have to plan out which "monsters" to attack and also have to try to figure out the order of the body parts. It is easy to run out of CPs and then have to either use magic attacks or defend until CPs return. However, another drawback is that if you already "killed" a "monster" it can respawn if take to long waiting on CPs to return and do not Seal it - which also costs CPs.
If the game designers would have left out the CPs entirely, this game could have been great.
