I'm planning a 2D first person adventure game at the moment. Inspired by 'Snatcher' on the Sega CD.Similar perspective but with on screen interaction via the mouse rather than the menu system it employed as you can see in this explainer video. I'm looking for some high-level advise on how this would be achieved.
My game would work like a normal 3rd person 2D game without the main character and instead of waiting for the character to reach a marker before being able to interact, the interaction would happen instantly.
I have search the forums but first person advise seem to mainly centre around 3D first person games.
I have also looked at Visionaire Studio which does have tutorials on how to implement this but I'd like to stick to Unity if possible.
