Seriously.
The titular game came to Steam recently and is the most fun game with ducks I've ever played. Not that I've played many?
I've seen threads about various games, albeit bigger ones, so I thought I'd make this to spread the word/maybe get people to play with.
It's perfect for local multiplayer, but unlike most indie 2D arena fighters like Towerfall, Duck Game has online play too. You customize your duck with unlockable "hats" and proceed to slaughter other ducks with a variety of weapons. It gets ridiculous quack with its tight controls and rapid feather instakill matches.
If you've got a spare ten dollar bill I doubt you'll be disappointed. There's also a 4 pack where you essentially get one copy free if you're friendly and frugal.
