Trial-and-error is an unfortunate reality in video games and is an often criticized part of game design. However, it's extremely common, and this is likely because trial-and-error gameplay creates tension, as the player is punished for using the wrong solution. A game without punishment for errors results in similar experiences to those seen in the cozy-game genre or walking simulators. There are exceptions, certainly, but trial-and-error is almost unavoidable in challenging games.
