A 5$ game that was worth just about that, five minutes of fun a night that would give you and friends something to do if you were bored or waiting on someone to get online.
Ridiculous, silly fun that also takes some skill and practice to get good at so it's quite rewarding beyond just the squishy noises and flapping dongs.
I know this is kind of considered a joke game, but the mechanics underneath it are genuinely fun, and I love it. I could play it for hours, climbing with the unusual controls and flinging myself up a pile of half naked men.
I think party games get a bad rep for not being deep but in terms of minute to minute enjoyment, Mount Your Friends is one of the greats. An easy recommendation for any party.
