Personally a bit too easy and does get repetitive at times, although Viv made me laugh a couple times lol
Stuff that would be cool:
If I got to a specific point in the game and a little short animation (maybe like 10 seconds) introduced the next part of the game (like going from the city to the street, or from the streets to the houses) it would have been more enjoyable
Oh and if the music changed like half way through and things got intense or something it would have been cool too.
Or if you somehow made it seem like I could progress to different stages rather than just 1 long stage..... I don't know how to explain but it would have been a nice addition to the game
Overall I did get to the end with everyone alive, so it was an entertaining game
