Regarding This End Up: I couldn't make it to the end, either. I did fly through it though and checked it out and it looked really nice. Maybe a checkpoint or two? Though I dunno if that could work with the concept, actually.

And thanks for the feedback on BollyWorld! I agree that it could get pretty chaotic with the copters floating away and whatnot, but I guess I just spent so much time playing it I perfected some strategies.
