Shops weren't my compliance to the people to make my game easier.
It has been in my mind for long already and that is why my game also has coins inside the levels from a period on when coins were available in PB.
As you probably all can see, until today, I have focused mostly on the levels, mostly special and boss fight levels and that is why my game also has become harder and harder rather than contrary. I also use some complicated mechanics for new obstacles, look, etc so a lot of levels can't be made easier that easily just by moving one or some objects... And I want my levels to keep looking a certain way as well.
Now, I have tired of working with levels like we all do when working with the same project because those cost a lot of time and I need some change. For some amount of time I now still plan to work with the same project for more efficiency but with something different in it. This would be shops, new intro about the creator and the game, new Land of Dreams and title and menus also.
