Monster Tale. A really under-the-radar DS platformer with Metroid-vania gameplay and light amounts of Tamagotchi monster-raising. It also has a sweet combo-system, purchasable upgrades for your character and your monster, a great soundtrack, and some of the best animation on a handheld this year. Track it down at any cost, or it may become rare (like Shantae).
My design is based on Chomp, the adorable little monster that follows and serves you throughout the game. Cookies and candy serve as powerups for Chomp, allowing him to get stronger and eventually change forms - hence, the cookie. I'm really starting to pay attention to the way other artists build their more complicated vector forms. There's still a lot of things I want to learn.
