Dex is a 2D, side-scrolling, open-world cyberpunk RPG with a focus on exploration and non-linear gameplay.
This game is a tad older, and time and time again, I'm surprised that nobody seems to know it. So, I'm just putting this our here, so you have heard about it ;-)
First (few) time(s) I played it with keyboard. I remember revisiting it with a controller and the experience not being optimal. I think I either tweaked it to my liking or just used some steam community profile. Either way, it was great after that and some getting used to.
