"Where I Go At Night" (Game, Male -> Wolf TF)

The TF is a quick sprite swap, but the real draw to the game is the concept and excecution.
"Where I Go At Night" is a local two-player VS game designed with a retro-game design similar to the 8-bit/16-bit era. Both players control the same character: some poor shmuck with the classic werewolf curse (man by day, wolf by night); Player 1 starts off as the "average Joe" going around town looking for elixirs to slow the transformation and set up barricades for the inevitable takeover, while Player 2 starts off as the werewolf, tasked with breaking the barriers and killing as many villagers as possible.
There are two rounds in each game, with each round lasting three days. At the end of the first round, the players will swap controls (P1 is the wolf, P2 is the guy). Naturally, who ever scores the highest wins.

Try it out with a friend (or not).

That's a cool concept at least. I'd love to see that done with higher production values and the option to select from female characters as well.
