The main mechanic of Further is an interesting idea (you go through color-coded rooms, that correspond to various memories, triggered by certain objects). The various settings seem completely disconnected from each other, in a kinda surrealistic way sometimes, which creates something interesting considering who the PC is.
However, this game seems to be interested in telling a story, various moments and memories that are loosely connected to each other. The way it accomplishes this is rather ham-fisted: you can't do anything unless you follow the "internal compass" of the game and go exactly where it wants you to go. Thus I spent the majority of the game following directions the game gave me, and that isn't a very good feeling in a game. Furthermore, there seems to be absolutely no objet implemented except the ones that trigger memories (even when the locations describe objects, they're not implemented), so you really feel like stuck on rails.
The game is really short, very very linear, and has a few typos; it's not a bad idea, but it's way too linear to be really enjoyable.
