Loved the game
Got Game idea from https://www.youtube.com/watch?v=DC8omKlH0Ns
Apart from basic upgrade of what you did
1: Detective / Lawyer mode (Happens in the day) that you use Daredevils abilities to make a case (For DareDevil or Matt Merdock), note that I mean only building the case if you want you can create or convert a cut scene (From the movie or TV series [convert to anime style]) like in L.A. Noire
2: Day and night should look different normal in the day and light red overlay at night.
3: A perk skill upgrade system should be put in place like ''seeing'' through a polygraph 5 times gives you Looking through the lie Perk which gives you the skill that tells you when someone is lying (at least for ordanary people or goons) so that while its progessive at the end of the game if you unlock all perks you should feel like a superhuman compared to the begining.
4: 'Skill tree' is available but takes time from your night events (a set amount of events are needed to obtain a skill) and can only be accessed in your apartment (It acts like you are training to get the ability on the skill tree)
5: A event time system at night (you can only do a finite amount of crime fighting at night obviously there is degrees and every crime that you hear is put in your tasks an most is gone the next day)
6: Warning system you use for incoming attacks gives your more reaction time when fighting fewer enemies because Matt has less to focus on.
7: Combat should work like Ghost of Tusima where your character gets better and learns better ways to fight enemies as you go. Like maybe when you unlock the Billy Club you have fewer grappling areas. But you can upgrade it and practice and get more and more access to its full abilities
8: Movement from assasins creed or watchdogs but Enhanced a bit till Gotham Knights
