Ashley, I was trying to reproduce a Adventure game using C2, but it was difficult because the lack of options around Z order, when you're doing "perspective worlds".
I think Our next big spot (or behavior) need to have some focus in that Z Ordering things, but that's another talk, for another hour ^^
About the Maniac Mansion, You can play it inside the The Day of The Tentacle, inside a bedroom, on that old computer looking like a CP500 ^^
