I was sceptical, though fascinated with the idea. Game mechanics are really thought through. It gives a good feeling of "being" the alchemist and discovering new potions is really satisfying. You can't really lose, but it's relaxing this way. I'm totally recommending this indie game for anyone who wants to relax.
Apart from that, the games is good, but it's very exhasting when a character dies and you ressurect him/her and need to get all their stuff from the ground.
