I might be uninformed (correct me if this is a remake, or something) but for me this seems a quite unique game, I love the 'innocence' of the gameplay, and the sounds & music is quite relaxing. Overall, interesting game, maybe more detailed models, and more "living" on the island would make it better.
Not figured it out yet, but the graphics seem cool, and there are a lot of things to find out. Lighting is a bit too shiny (and raytracing? It really seems like it), but still, quite good job. It is always good for an escape game, where you start in a normal, everyday place, like a small room. :) 4/5
Well, its maybe a spoiler, but you have to place the hacking tool on the door-opener-pad-stuff and it tells you if the number is bigger or less than the number, you need.
BUt you can get the number in an other way too, seems like you found the easier way. :)
