It looks like the type of game I like (unfortunately I couldn't play with anybody these days). Local co-op was a brave take. On top of that, the graphics are neat.
I just wanted to warn you that, when playing on the browser (Mozilla, running on ubuntu 18) if I try to attack with the knife ("c") while moving forward, it crashes every time (player 1 was the first class, player 2 of the second one).
