Well, I decided to scrap the lerp camera in my project for now. It's unfortunate because I really liked the effect it had. After reading on the subject, I have come to the understanding that Construct 3 isn't fully capable of supporting a lerping camera without causing variant degree of jittering (for platform games); At least not easily... I guess there's always a way, especially since you can add your own JavaScript to your projects etc. But, I wasn't successful in trying. Eventually, if I get it to work, I'll post the solution here.
