I thought you should know (if you didn't already!) that my housemate had some issues playing this game using a touch screen computer until he started using a touchpad. When he was clicking on stuff it was like it registered but didn't affect the game in the same way (for example, he couldn't get the pigs' eyes to shut at the start.) I don't know if it was just an issue with his specific computer but just thought you should be aware if you ever have anyone complain of the same issue! :)
