Thank you so much for playing the demo of Heart Fragment! As for your question, that definitely shouldn't be what happens so you might have run across a bug. Have you run into that issue when doing that mini game with anyone else, or is it just Gray? Either way I will try to get to the bottom of it asap. The first release is coming July 31 and the mini game has been refined to make it easier for people who play with just a mouse in hand instead as well, so when that update is added to the demo I hope it will help this as well.
