Once the limited set of actions that will raise statistics for the day have been completed, the rest of the energy can be used doing random things that will raise RWC -- playing dolls with Cream, or trying all the different things at the mall, etc.
Toward the middle of the week, once statistics are high enough, the player gets new opportunities.
Some actions that don't get good results early in the game will get a better result once statistics have been raised high enough.
For example, if the player visits Cream in her room and asks her to take off her dress, she will refuse at first.
The current ending is incomplete, but it has a few drawings as teasers of the eventual, complete ending.
