In adventure video games, there is always a moment when a totally obscure element that frightens you with its apparent complexity suddenly becomes obvious, crystal clear. The player's satisfaction is then at its peak, having then understood the incomprehensible, experiencing the duality: being proud of oneself / castigating oneself for not having understood sooner. This is exactly what happens in "Existence", a game that have everything to impresse with its first impact, but which proves very accessible as soon as you become familiar with the clues. Well done !
