Thank you very much!
I've worked on the Art most of the time I had for this game.
First we had the system on our game, that the hearts would land directly where you would aim, but I felt like this was too easy, so I changed it. I wanted to create something challenging, that looks simple and is easy to learn but hard to master. Now, after the Game Jam we want to implement an Online Leaderboard and a Reward System to encourage casual play.
