Thanks for the feedback. Yeah what you describe about the physics is pretty much what I want, inputs influence physics instead of directly the character, kind of like Monkey ball in a lesser degree. However you dislike it while I like it...
About the camera, since I prefer this kind of smoothing I suppose everybody will have different opinion, so I'll just add an option to increase or decrease smoothness in the options later.
I might be copy pasting this a bit, but since I went through the trouble of making it to answer people about the controls, please take a look at this video. We might not agree and it's totally fine, but I won't ignore your opinions neither, knowing you feel this way helps, so thank you. ;)
