It's an odd adventure that starts quite slowly, but gets interesting after half an hour or so. The puzzles are easy and just there to keep you exploring the site and the story. Aside from the start the game delivers an unexpected level of entertainment for 4-5 hours. 20€ might be a bit steep for the average consumer, but I think the game is a no brainer on a sale. I basically only downgrade it a bit for the current price, at 10-15€ I would have nothing to complain. I really hope the game does well, because I'm hoping for a sequel.
