I was intrigued by the time travelling concept but none of the levels felt like they were especially built around that idea, I never really felt like I was trying to solve a platforming puzzle, more just that I was platforming. I did really like the idea I just didn't feel like the levels were refined around it. I liked the zany art style and your title screen has a lot to appreciate (even if I was never a big Dr Who guy)
Also I was soft locked by the palm tree and couldn't get out without refreshing my browser.
