Glad that you've been enjoying the game! I've tried to make an adult story that keeps the player's interest and it seems folks have appreciated it!
As for the reduction in choices during week 2, I think that's a result of the number of potential routes being whittled down. Once you start interacting with less characters, that only leaves choices inside their actual scenes. For week 3, I'm hoping to add more of these types of choices and they will definitely have an influence on the final week as well as the endings. Thanks for the feedback!
