A neat idea of a game. If it will be a fun and heartfelt game will depend on execution. I sure do hope there is a mixture of good and bad endings because face it, people abandon their dogs way too often and the ending to that is a dead dog. Still though, I can see ways it can be made into a fun game. Since this is a Kickstarter, I don't want to speculate too much but the end game stuff could be reuniting with the previous owner or getting a new owner through you charm and wits.
