Return of Egypt is a pretty competent Castlevania: Symphony of the Night clone that has you playing as frickin’ Moses! I’m not really clear on the story, but who cares. You’re Moses, and you’re back to kick some undead Egyptian ass. Just like in the Bible.
The author definitely intended this one to be played with a gamepad, and some of the special moves are tricky to pull off on a keyboard. Gamepad is the default control scheme, too, so hit F4 to change your control if you need to. Spacebar reveals the map.
EDIT: Changed the link the Acid Play, since people were having problems with the Underdogs.
