The sprites are cute, good work on that. But there are some problems. First off, the pixels are all blurry from Unity. I agree with @SpaceDogGames, Unity is likely not the right choice for this project. Second, they shift around strangely as I move. The camera lurches and pops. The controls can be much better. Running is fine. The jump height and speed feels good, but you slow down when you jump and when you land. Not sure if it's intentional. The wall climbing can definitely be improved a lot. When you do it, your control of the character is virtually taken away. That doesn't feel good.
You clearly have an interesting vision, and there is a certain mood you are beginning to develop here. But you need to resolve the technical issues of control and presentation before that will really start to come through. Keep it up.
