There should be added some things, e.g. every day another task and a visible enemy chasing you. Otherwise it gets boring doing the same every day to please him and get to bed afterwards. I'm not sure if sacrificing yourself is really a good ending. I would like to see "God", eventually as final boss that can be defeated. It's a good idea, but the scenery looks a bit empty despite the "sacrifices". It would also be great to get to know something about the background story after each day.
