i got great feedback from you on my game and I try to give a little bit of that back. your concept is super interesting. but i had a hard time understanding the rules of the game. two ideas on how you might improve that and make your game easier to grasp:
1. reduce the instruction page to the most important stuff. at the moment it is really a big wall of text :)2. a gif or short animation at the beginning showing how to correctly zap a stone
