I hope I did this right, sorry first deal! :P I know there's a remake (Rebirth) but at 0.66 USD you can't go wrong with this deal as it also comes with expansion Wrath of the Lamb or if you just want the standalone game at $0.49 USD. Really looks like a fun game in my opinion.
The game is easily worth 20x this much, I sunk over 100 hours into it without getting bored. Fantastic game.
