I do like the concept of this game, I understand that the intended concept of what gameplay looks like would be to run around and collect hearts as they disappear and reappear while avoiding saws, however I think there are some major design flaws that might confuse or drive away a casual player, first when the time runs out it does not take you to a lose screen (or a win screen depending on how many hearts are collected) but instead the hearts and saws stop appearing, this may confuse a player as to if they have won or lost as they still have control of moving the sprite around, secondly I never felt like there was a real threat from the saws as I only encountered them 3 times over the course of the gameplay, which made trying to get to the hearts the main goal instead of also avoiding the saws, lastly when you do collect a heart it sort of halts movement for a second which prevented me from collecting a bunch of hearts when they appeared at once, I feel like if you fixed those errors this game would be more exciting for gameplay, the concept of the game however was certainly great!
