Just tried it and it worked for me, got Droid Assault as I alaready owned Revenge and Attacks. Solid little games. I suggest getting Revenge if you don't own any of their games yet.
Edit: Looks like it's getting some heavy traffic so if the site is borked try again later.
Edit2: if you choose Revenge or Titan Attacks, you can get a Steam key via this link: http://www.puppygames.net/steam/
