My heart was POUNDING with adrenaline when I played this. I didn't think I would have gotten that feeling from a game like this.
Not only were the mirror levels difficult, But The platform part of this game also became harder and harder as it went on. In the beginning, you were allowed to be sloppy, but then you needed you to use your double jumps and dashing as precisely as possible near the end.
I became more and more frustrated as I lost, but that just made me want to beat the game even more. I didn't get a satisfactory ending, but I made it to the end nonetheless.
Great game, great concept. Keep it up.
