Thank you for the kind words! Glad you found it fun! I made the dog bark quite often when it requires your attention.
About the lag, were you playing the HTML5 version? You could try a native version... I had it tested on quite a few machines and it played fine on most. Only one struggled and couldn't maintain 60fps... It was an older machine (Sandy Bridge era) with only Intel integrated video, which just aren't really designed for gaming. However that person was still able to complete it just fine.
