I finally finished my entry. If I get enough time, I may update it; but it’s polished and in a playable state right now. It’s also quite fun to see yourself die in horrible ways; even if you have the best weapon in the game (called “The Reaper +15”). You can find it in the submissions menu; http://www.ludumdare.com/compo/ludum-dare-15/

Edit: There was a bug in the game in the Altar sequence. It’s fixed now.
