haha, just kidding. I found that adding in a feature (bonus items) seriously changed the flow of my game. It made it more exciting, a bit easier to win, and really put it over the top.
If it's possible to try it out without too much time, it may be well worth the effort.
You're right it totally change he flow of the game. I can't decide right no so I added a toogle to enable/disable it for the week-end. I will have to make a decision monday morning ^^
