Lol no, i'm sorry but the game would end up being repetitive and boring to play with your suggestions, it's fine as it is, he just needs to work on the map and expand it, add some roguelike elements, more animations for the girl and maybe even a story mode.
the problem with games like this is you dont want to auto kick into action it just makes it even more repetitive with the elements below it allows for choices and also allows for some breathing room for the player but whatever you think we are all diffrent and i personaly think the main killer would be annoying to deal with and could even end up just at a stalement 24/7
