This picture shows the concept of "trial and death" from the video game Limbo (2010). In the picture the player (indicated by the yellow dots) will need to change his environment by, in this case, stepping on a switch in order to advance in the game. The two pictures shows the situation where the player fails to step on the switch, which results in a death (top picture) and the effects of stepping on the switch and using the box to continue on in the game (bottom picture).
