Thanks for the feedback! Don't know which version of the game you played through, but in one of the more recent updates I made it so that the player is given new Side Quests at the start of the post-game to give the player a reference for what's left/where to go.
I grappled with this idea for awhile. On one hand, I wanted it to be like the old days of video games - like the dedicated player finding reward in discovery or two people sharing a moment in swapping playground rumor stories. On the other hand, and the hand that eventually became reality, it's just better game design. Players would have become accustomed to the Quest system by then. Not giving quests for post-game quests after they were explicitly mentioned in the credits is awkward. Plus, giving the quests will queue players to experience more of the world I had crafted, which is always a fun thing.
Anyways, long rambling over. Thanks again for playing my game! I really hope you enjoyed your experience!
