Thank you! Super glad you like the game! Really great comment! I am using Godot, just thought R = Reset Haha, I am considering to build a UI, and put some sth including reset button. About another one, sorry for your confusion. I sent it to one of my best friend the next day after the deadline, and he complained exactly the same, now I can see more clear that I cannot design like this. Rebuild this feature and some of the levels are definitely on my list.
