The last game I played was a game that was recently greenlighted on Steam. It's called "Who's Your Daddy?" and is pretty fun.
It's still in an early stage of development and is full of glitches. It's a two-player game where one person is a baby, and the other is the baby's father. The father's goal is to baby-proof the house to prevent the baby from killing themselves. The baby has access to all sorts of things, like forks (and of course, an electrical socket to put the fork), drinkable cleaning products, and other dangerous things that a baby shouldn't have access to. Right now, the difficulty is pretty lopsided. Both of the playable characters are overpowered. The last time I checked, the game was still free!
