What's easier and quicker than right clicking is holding down the mouse button on the boulder level right where one of the bottom three tiles is going to be. Achilles even says to hold down the mouse button in the game instructions.
For the vending machine, you insert the left coin, insert the right coin, push the red button, hit the side of the machine, click push, then click the red button that appears. For the praying dude, click the hand.
PS. my best time is 2:00:51
So far my best is 2:02:30, which is maybe a second or two off from perfect. Great game, good replay value in trying to get faster, and some of the ideas seemed pretty original. 5/5
