Very nice! Love the art effect of leaving behind a trail of where you where + the animation looks very nice! And works very well to trace back my path. The idea of playing the game again but not controlling the character but only the timing is great! and the main character looks very nice!I
I did have problems with the replay button, why is it there if i finished the level but also its way to big and easy to click in a hurry (like i did the idiot i am). And i would not use the backspace button its at a weird place to use and play the game i think personaly. Other than that every nice and looked and felt great!
And i maybe its an idea to give the red diamonds more meaning. I did not really feel the need to pick them up after failing to many times and just left them there. Maybe it could be money for a shop or like collecting letter or something so i want to pick them up other then just a score thing.
Overall i really liked it!
