Costume Quest

Costume Quest (and its sequel) is a plot-driven adventure RPG, story being light-hearted family-friendly comedy about magic of Halloween.
When your twin sister/brother is captured by strange monsters hoarding candy, you need to go to the rescue, while picking up new friends, collecting experience and candy (money) and new costumes giving new special powers and fighting nasty monsters.
The game draws some of its influences from JRPGs, including cutesy look and fighting (turn-based line dancing with regular and special attacks).

I'd guess the reaction to the game is dependent on expectations and how one plays the game. It is quite light romp, never getting particularly difficult but having enough activity that it's not just clicking to the next scene. Battles and quests are a bit repetitive but the game moves forward just such a pace that they don't get too boring.
Despite the story-heaviness of the game it is still best experienced in smaller segments for casual play, an hour or two at the time (maybe together with family members), trying to play this through in one sitting would probably make the game appear boring and lightweight while a casual adventurer finds a pleasant experience.

At least in Windows the controls are sometimes a bit clumsy, but not to the point of frustration (casual difficulty level of the game helps here).

Gamers champion Double Fine Productions for good reason: It’s one of the few developers brave enough to focus on comedy and unique stories in a medium filled with space marines and melodrama.

Rather than controlling a dragon slayer, Costume Quest is a roleplaying game where you control a prepubescent boy in a costume that can morph him into a giant arachnid with fries for legs, among other collectible transforming outfits.

You go door to door looking for your sibling on Halloween. Some doors will lead to a battle encounter with monsters, while at others you will meet a friendly neighbor who will give you candy that works as the game’s currency. That’s about it.

The art design and dialogue are saccharine to the core. Like a bowl full of candy, Costume Quest is a cheap, brief treat that lacks substance. Nevertheless, I can’t think of a better game that captures the spirit of Halloween.
