Ghastly: A puzzle/platformer game about a girl with a rocket launcher, and her ghost that mimicks what she did before her death.

Note: The game is fully playable and still great in-browser, however, becomes more unstable and lacks textured particle effects (the entire explosion's impact is gone). I recommend you play it downloaded, but you can still play in the browser if you'd like. PC/Mac/Linux are all available for download.
