So I just played your game. I really liked the creepy atmosphere it gave. The choice of music was really good, although I kinda wish there was either a corelation between volume / speed of the music or possible some other sound effect to hint towards how far away you are from the monster.
I *really* loved how you did the credits with literal links to the product, that was cool!
One time I rewound into the monster, not sure how that happened. Does the monster not rewind? Or?
I liked obarroso's comment about having an event to help demonstrate when would be good times to use rewind. I tended to use it to try gain more time. But it also confused me even more when I did so since it took me back to a spot in the maze that has no references. Which leads me to my suggestion -> Have a minimap for the walls. Don't need to show the gems or the monster. But at least if there is some context as to where I am it feels a bit more fun, and a little less brutal.
Does the monster ever lose track of you? I was just wondering since how the music comes on. Not sure if you he just always knows where you are or not. I did find that I was able to run straight past him though which felt a little weird, I was expecting him to lunge and not allow me past.
Granted, I lost track of the main objective because of trying to avoid him, so I haven't actually gotten to collect them all yet haha!
Was a good experience overall though to be honest! Nice job! Also so far haven't seen others on the horror/scary theme so that was different.
