If it was not that much niaiseux. But it's not that bad and the game story is good. Also, I'm not really agree with how to complete the game at some part and I won't talk about this in depth because it would be a spoiler. So this is two reason why I don't give it a 8.
The graphics and art style is impressive and run well even on a laptop. The sound and voice actor is perfect beside the music that like in all games could be better. The 3D experience is better than the 2D and so it's a good evolution.
The gameplay is superior to King Quest 5 but the story is more humorist and I'd prefer the old story style that contain humour but not that much and not that much niaiseux. The story make me believe this could be a good game for a family and I'd for sure play this with my child.(I've played it in English so I did not understand everythings(Even if the game would have been in French I bet I could have not understand everythings.))
The quest or the puzzle goes to easy to medium hard. They are all interesting. There is also the mini-game that work well and give some cool challenge. Most of the quest are passable by logic so the game make a lot of sense and I don't think it was making all sense of what my memory can remember in the old King Quest 5. So it's better now and more passable and finishable without walkthrought.
I think that for 10$, this is a worth game.
I finished it without walkthrough and cheat and it's rewarding. Do it too and don't give up!
