I liked the concept (and my team initially had an idea similar to this so I'm biased), but the tutorial really confused me. Probably I would have understood it better without the tutorial, but I guess there might have been a mismatch between initial intentions and final result?
Also I was confused by the hearts since it's a one-round game, but I think that might have been also a missed feature.
I liked the style and the animations and the music too! The timer probably didn't quite work with the gameplay unfortunately :(
Also as a side note, I think you uploaded the development build instead of the release build, hence the folder named "After Round One_BackUpThisFolder_ButDontShipItWithYourGame".
