Some more thoughts.
Looks at which game gifs go viral. A lot, of not most of them is where somebody does something hilarious, stupid, and likely lethal. Your game has a perfect premise for that. Look at those gifs, invent something like that for your game, and work up it.
Also, about graphics. Maybe try and do something yourself? Maybe just a geometric shapes. With eyes. Angry Birds is basically this, and it works. You can just make a rectangler, but with big and very emotional eyes. So you really see when it's snoozing, or it's chasing player, or horrified when falling to it's death etc.
