I love the sound effect! sounds so dark! and is that a voice mixed in as a sound fx? nice :D really liked the sound overal spooky and empty but worked. Also great with the visuals all fits in nicely. like a 2d oldschool portal vibe ;) But the controls! damn! there very confusing the use like i'm getting punished, keep pressing the worng buttons :P and a short pause/ brake after the rewind would be very nice. or other ways to start time again. i was more battling with my keyboard then with the game :P
But joke aside, i really like the game! with better controls i would definitely would love to play it again!
