Gesundheit! was a mobile game for iOS and Android. Unfortunately it's no longer available, as the costs of continuously updating an older game to comply with changing mobile platform policies became unfeasible for the game's publisher. (Although the soundtrack is still available on Bandcamp.)
RIP little pig!
