About the lagging, I don't know what is happening because I've just tested out both the online and offline versions of the game on my fastest i7 computer and also my i5 computer and they run just fine without any lag. Are you using an i3 computer? I know you're using windows since that downloaded version is only available for Windows 64 bit, but if you use an i3 computer it might be why it's lagging.
My laptop uses Intel Celeron N2840:
It's been running a lot of visual novels by Ren'py creators and professional studios flawlessly (CloudNovel is a first), although it does appears to be even worse than an i3. x'D
