Thanks for your comment and suggestions! The control scheme allows players to move both characters at once. Lea is moved using entirely using wasd and Sera only uses the right mouse button. Sera's interactions, attacks, and movement are all mapped to the one button. Sera's attacking behavior is reliant on the state of the enemies or their distance from her. I am still working on a joypad scheme, but it would definitely require an auto aim. Your idea of an auto combo system is interesting; I could simplify the attack system even more by including a button where both characters attack the same thing or allowing for auto attacking as an option.
Sounds good already then! Just a thought given the project, but yeah it would be a neat experience to have control of two protagonists both capable of real-time action. I've been playing Pragmata and it sorta does the idea between the hacking + shooting in real-time but not quite the right feel for what I was thinking. I will definitely track your project though, a cool idea all around.
