Demon Stone is clearly an action game in which you can upgrade each character in an rpg fashion, but you will probably get all the available upgrades, or at least most of them, for each character till the end of the game. You will fight tons of monsters throughout the game's chapters, using each character’s abilities, by continuously pressing your left mouse button... In most of the game you will be surrounded by dozens of monsters, abusing your finger and your LMB waiting for them to get hurt... It becomes a little more fun when playing as the rogue, as you can disappear in the shadows and use sneak attacks on an enemy or two afterwards. Some combos do exist but they are actually useless and silly looking. They take too much time to accomplish and you will probably be interrupted by an enemy before you complete them or you will end up hitting the air, since the enemy will have probably moved from the place you were aiming. There is no lock on enemy feature and the controls are bad. There is also no gore. You will know when you have killed the enemy only when he disappears after he falls down... I played the game in normal difficulty and it was quite difficult, annoyingly difficult most of the times. The levels are really small in size and you are actually stuck in two or three places in each chapter fighting monsters or the chapter boss. The graphics are good given the age of the game and you can see the character upgrades on your character (armour, weapon upgrades etc). But the environments are quite uninspired and restricting. Also you will not be able to "admire the view" since you have no control over the camera.
Voice acting is nice. But other than that the game doesn't sound good. The music is tiring and repetitive and sound is very limited through the game. Weapons make no noise during the fights.
Well what is good about this game, apart from the voice acting, is mostly the characters which seem quite alive and interesting during their dialogues and interactions and the nicely presented story (although it lacks any originality...).
My first game review is already too long, so I should better end it here...
