Absolutely LOVED the Art! The Old Monitor style is a nice touch too. Really simple and fun to play :).
But i think you could improve some things. First the walking animation, when you stopped moving the animation still play a bit. Also the rewind mechanics of this game, I feel like it didn't play an Important part of this game, hence, making it just like another timed game. Just a little audio can improve this game significantly.
But Overall this game is fun to play and you should definitely continue to develop this game.
Consider rating & giving my game some feedback too.
