Beautiful and simple.
The Plan is beautifully created. It has been created with a strong sense of enhanced realism. The conifer forest appears very real albeit obscured by peripheral blur and depth of field. Before you reach your final destination, you witness a nebula in the background, before you become aware of a source of light directly above, as evident only from a shadow you cast below. The Plan makes astounding use of Unity, an engine which isn't known for its graphical capabilities.
The Plan's website states it is a game 'exploring issues of death and meaning'. It is a personal experience and one may infer their own meaning from the game. For me it explored a deterministic view of self; the inability to sway from one's path, the futility of our conscious goals, the pointlessness of our legacy and our inevitable, our meaningless death but also, the beauty we find around us and the ironic, ever increasing void in meaning to our lives as our knowledge increases. To some extent, in a less metaphorical and considerably less pretentious sense, the perils in exploring the unknown.
