I'm developing an action horror game where almost everything even the combat, relies on both characters. The combat is in real time, with a simple control scheme and a slowdown function to allow players to easily control both characters at once.
Some background info:
Story summary: An unknown event merges strange beings and objects from other dimensions into a biology lab. The story follows a slowly mutating security guard named Sera and a junior scientist, Lea in their attempt to escape. To make matters worse, a mysterious entity has latched onto the remainders of Sera's left arm. While it's given her a boost to healing as well as strength, there are some yet to be known side effects.

Combat: There are different attack effects when attacking with Lea's variety of weapons. For example, one specific weapon allows Sera to pull off a fast kill. Sera's attacks with her sword arm weaken enemies, resulting in them taking more damage from bullets. Unfortunately, Sera mutates per hit so you can't just hang back and let her do all the work. I like flashy action combos in my action games, so I brought some of that to this game.

Puzzles: Some of them require the usage of both characters in possibly unexpected ways.

Any feedback is heavily appreciated! At one point I'll probably cover design considerations since there were a lot of things I had to think about when designing the controls. In the past I received some concerns (from people who hadn't played the game) that a dual character game would be hard to control or overwhelming. I'm currently working on the boss for the first level.
