Midnight Realm (MaskedIntrovert)

Midnight Realm
Halloween 2009 Contest (by Darken) entry.

Game
Midnight Realm is a light-hearted high-speed puzzle game; it's design to be simple and fun and only take a half hour or so to beat.

Story
You play as Jeremy, a young and jaded gamer who doesn't feel Halloween has any meaning.

Unwillingly transported to the Midnight Realm, you'll need to run a few errands to get back home before you're stuck there forever.

Gameplay
You choose a class and are granted a series of skills, you combat enemies using an auto-attack combat where instead of choosing Attack you spent your time using a puzzle-like grid to recover health, restore lost SP, increase attack and defense, and get skills which you can use with the Z, X, and C keys.
