I have to say that the game is not bad, but I found a bug during a few gameplay throughs. If you go outside, instead of going to the door, you can close the other door from the outside and then go back in. However, even if you do have the door open, he walks right through the door.
I would expect alternative endings too, for example, if you do manage to do what I did, the game and customers would continue coming, and then during one of those refills, he jumps and kills both or something, I would just expect a different ending.
It would be good to be able to fix and restock the 3A counter, just an idea. It would also be a good alternative, a good ending, where you can call the cops after you've spoken with your boss, because that is what I would have done. So those are two more alternative endings, and I am sure you can come up with more.
