Many people how complained how Proteus is not a real game, either due to lack of challenge or clearly defined goals.
What I experienced was the purest form of a game in a long time. From the very first step I have “played” with the surroundings, with sounds they make and was trying to figure out this world. The mechanics are unkown, the goals even more so.
Only way to find out anything was to “play” - to try out things and be constantly amazed and surprised at everything you see.
I think the strength of indie games is the fact that they are not bound any sort of rules. I have played lately a small horror game called Transition and you know what the most horrifying thing was? I didn’t know whether I could die or not.
I didn’t know what rules the game has set up. Is the beast going to kill me? They gray dots obscuring my sight, are those deadly too? Or perhaps I am dead wrong and those things might be even the only way to win.
These games require an open mind or perhaps it’s them that open up your mind.
