This new build adds an arena like environment, and makes the sensei character react more to you and throw rocks more aggressively. The idea is to build this out more, with the man being able to say stuff and keeping score. As currently there's no way to win. That's next. 

Also added in a way to launch rocks one by one instead of all at once to add some speed to it, and now there's more small rocks spawning in the world for you to work with. The rock slicing also doesn't require you to have the rock picked up, just point the white dot at the rock you want to slice.
