Completed with 100% of achievements unlocked (200G). Costume Quest is a short, simple RPG with a Halloween theme, where the player takes control of a small party of children out "trick-or-treating". The game revolves around collecting parts of costumes that serve to facilitate puzzle-solving and to grant combat abilities when facing off against enemy monsters which roam the environments and sometimes inhabit the houses that you visit seeking candy. Those battles are the second major part of the game and again fairly simple, with your party facing off against monsters in a turn-based fashion. Combat abilities are limited to a basic attack and a costume-specific special with a three-turn cooldown, with the only additional depth coming from equipable badges. While these mechanics are clearly rather basic, the game as a whole is elevated by a wonderful sense of charm, typical of Double Fine's games, so it's a decently fun time through the six or so hours that it takes to play through to completion.
