I am fairly new to C2 but I find that as long as any individual layout isn't oversized or too 'heavy' then C2 works very good.
If you have , say, 1000 pages on a single layout then you may have performance issues,
but as long as you keep any individual layout 'light' then I think you
will be fine,
for example, I recently made a Kids Alphabet game, sliding from letter to letter, etc,... I first made it all on one layout and it was very slow on mobile devices, so I simply made each letter on a separate layout and preload only the needed sounds for that layout... it now works great and I am able to add extra things like sine behavior, etc to the game to make it more fun.
So, you could make each page on a separate layout, this way nothing gets bloated and you can have more animations, and effects on each page enhancing the user experience.
C2 is so easy to use too. I recommend C2.
How many pages do you think you will have?
Anybody with more experience want to chime in?
