The ending is the end scene in each path, you can still keep playing and view other content tho'.
Got it, but since the vacations were stated in the beginning to be around 2 months long I expected that after said timer runs out we will see Michael and Sheila return home with behaviour and actions depending on which route was taken.
Instead there is no clear sign that the game is finally over and so one could mistakenly believe that there is still stuff left to do.
It would be cool if Sheila at least started treating Micheal differently after completing the game in each route like acting perverted/corrupted in the manipulator route and flirty/romantic in the romance route. That would be a great way to both make our choices look meaningful and to make it clear that the route is over as is the game content.
Anyway, congrats for this game. Had fun:)
