A platformer/shooter with emphasis on exploration, ala the Metroid series. Development began as a test to see what I could do with Game Maker, and expanded from there.
Here are the first few minutes of the game. If you've played the demo, this is nothing new, but there are a few modifications here and there. There's a hiccup at about 0:57 but that was the result of the video capture software, not the game itself.
