Really cool game! Dragging the hand to buttons being the way to navigate the main menu and options menu was a genius way of introducing the player to the hand drag mechanic, and immediately got me into the flow of rock climbing. I was a little confused at times whether my hand had successfully grabbed onto the rock or if it had missed, since both a successful grab and a failed grab played the same "pop" sound effect, so maybe consider different sound effects for successful/missed grabs. Overall, really nice job!
