Here is a little video I made to demonstrate how ZC is capable of side-view scrolling platforming.
It is a little buggy but functions at the 60/60 fps and plenty of room to add more functions. In fact, I didn't even delete any of the functions that I put into my last demo, and just wrote the sideview scrolling into it, so technically it could still do all the other functions of the Mirror of the Moon demo and then some.
I wouldn't expect a full-fledged quest from me any time soon, but I'll probably publish the results to AGN at some point by the end of this year for those of you that still might be having trouble with ZC's capabilities in the recent 2.5 builds that are awaiting a release of ZC3 for scrolling functionality.
