Post any ideas for routes you have here. I think you should do the faster levels which are first 3 to 5 and get all chameleons in them. And then, just get 1 or 2 on every level afterwards. At least for World 1 anyways. For world 2, its optimal you have all the chameleons before starting. For any%, I think u should follow world 1 route, but get all chameleons required in world 1 itself.
