Thank you!
The "too easy" thing was definitely an expected trend. I designed all the interactions to be extremely easy and playtest with my wife (who is not a gamer) so I could tune it down enough to make it reasonable. I have had a lot of success with this in the past; if it's a little bit challenging for her, I can be confident that it is pretty easy for most people who play games. :D
I'm glad it felt feature-complete. Learning and putting all that backend stuff together and getting it to work correctly took up the bulk of our time on the project (this is only my 3rd small project in Unreal; I have always been a Unity dev). I'm happy to know it paid off!
