Do all game devs experience similar types of abuse, or only the devs of games with environments in which the developer's company is attempting to monetize the player as they move through the game? For example-- there is some beautiful sidescroller game I've seen where the animation looks like old-school Fleischer studio cartoons. Do devs of games like that get abuse from players, too?
Sounds like the game you are referring to is Cuphead in which case I am pretty sure the devs for that game are getting plenty of abuse from players.
