It requires some luck to get that setup tho :D
I may remove 7's after there was a hit, so it wont obstruct the reels, nor the shop. The general idea is to introduce new symbols later, like 7/muffin/milk, which have varying effects, like outfits, body changes, or anything else, that seems to be recommended by people. Some other, very different endings are in the pipeline too with improved graphics.
