Believe it or not, I liked playing Cave Dweller. It's well made and extremely challenging to play fast I believe a run of perfection here would yield a time in the range of 1:52.xx to 1:53.xx, unless of course a new trick is discovered. I was able to jump across the top underneath the zip line from one side to the other but then I died. I am not sure if it would have saved time but it was really cool anyway
