Thanks for the feedback! I really appreciate your time for playing and writing the feedback. I hope you don't mind me addressing some of the points.
Regarding card effects, there are some parameters that weren't shown directly as city stats such as population growth, commercial rate, etc. But you can actually see some of them by hovering on the funds or population box. But yes, it would seem like the effect does not take place if the changes weren't shown directly in the UI.
I can see how income collection will become tedious over time. It was meant to be an activity for the player to keep them engaged with the gameplay but it would eventually be annoying as the city grows. There's actually a service building that could collect income automatically but I guess it's too hidden.
Buildings or effects that change attractiveness are currently not working since the game constantly calculates attractiveness from city stats. Will address that in a small update this week alongside some minor touch control issues.
Notification looks like a good idea to inform players on building unlocks. Might look more into that.
Security and health were actually planned to have more of an impact on a planned future update where you can dispatch ambulances or police cars for dynamic city events such as medical emergencies or robberies. Education will have more impact when a planned citizen simulation and career development system have been developed.
Thank you once again for the feedback and suggestions. I would look into them and hopefully can address them on future updates.
