About Mulligan Keep
Mulligan Keep is a cooperative deck building dungeon crawler where you play as one of four adventurers delving into a mages castle with up to three of your closest friends. Play cards to help you dodge monsters, escape traps and find your way closer to the hidden artifact. But don't take too long as the more time passes and the louder your group is the more the dungeon collapses in around you.

First off, HUGE WIN: all sounds are defaulted to off on first launch instead of being set to 5000%. However, could not finish more than one run because of crashes, breaking bugs, and general sloppiness. Game says it supports 4 players, but lobbies disappear after 2 people join. Lots of bugs and breaking7 found this helpful
Pros: cool art work, cool concept of a coop deck builder, cool cats Cons: not playable in this current state4 found this helpful
A co-op dungeon plunder game where you cannot make too much noise. I would rather scrub toilets with my time. Maven was a terrible wrestler so thus you get the red thumb of doom.1 found this helpful
i love the idea, and the concept is there. just needs alot more sounds and cues for when youre doing something right or wrong, what to actually do, and a bit more to be. gonna def try and win a round at some point
Couldn't see anything
I had no idea what was going on, trap time loops are too fast, and the tutorial did nothing to help me understand the game.
