My first puzzle... lots of kitties to win! [GA Ended - Solutions Inside]

So! I've decided to make my first puzzle contribution to the forums. I've recently joined the community, more of a lurker. I really enjoy how there's a nicely developed culture of solving puzzles to enter giveaways. I suck at most of them, but I guess I'll get there someday :P

I made the puzzle a screenshot guessing game. I've picked 5 obscure Gamecube games. Why Gamecube? Because I damn loved that system growing up :P I have some 80+ games for it.

Note: all games to be won involve kitties in one way or another, and all games are unbundled steam games. Have fun.
