Nice game, I'm sure if someone is a real puzzler guy, who likes to figure out all that stuff (I watched the tutorial) he might overtime figure out what to do, but espacially in browser (wehre files are hidden somewhere on yoour computer) it is a chalange.
Definitly now low entry barrier for this game. But visuals are great, fits the theme nicly. And yes, you have to hink outisde the box ;-)
