To clear things up:

I entered both Puzzle At Mystery Manor at the same time. It was by a stroke of luck that I won both of them.

I won Spriter: Game Effects Pack both by mistake, and cannot be redeemed due to the fact that I already own it.

Mahsung Deluxe and Puzzles at Mystery Manor are redeemed now - I simply forgot to redeem them. Runespell Overture was given to a friend because he really wanted it (I know that isn't what you are meant to do but I was being nice).

Hopefully that clears things up.
