Sonic

I was watching my 4yr old cousin play Sonic on the Xbox over New Years.
There was this switch on the wall and you have to press X and then push it into the wall by pusing up, or down to pull it out. He must've spent a good few minutes trying just to get a hold of the switch. With Sonic being a fast action packed game, a few minutes spent on any part is a long time. I began wondering how long it would be before he gave up, how long is a 4yr old attention span, or at least his commitment to pushing that button. Anyway he eventually got that button pushed into the wall and a door opened with something good inside.

Perhaps I could incorporate a similar idea into my game. For instance shoot a special buoy and suddenly the camera zooms out and there is a (metal? ) passage/tunnel on the left, you can go through it, whereupon you find some goodies. Then when you reach the end of the heavenly tunnel, you rather speed backwards where you came and the camera pans right, or there is an exit on the right for you to get out, and then the camera resumes normal playing zoom level. So perhaps a tunnel in the shap of an elongated straight C.

Just an idea though, perhaps a good way to avoid certain enemies, perhaps not a metal tunnel but a wormhole?
