Not supporting the host service is the reason why NoPy is shutting down... Just dropping this information. There is no free food, someone has to pay it whatever happens.
Mega's limits are a thing so people subscribe to their premium membership - and obviously, they aren't very good regarding quota limits enforcement, or more probably they allow it on purpose in order to let clever people download whatever they want and force the others (and the lazy ones) to pay for the premium account.
BTW, NoPy was, at most, at 8 MB/s for me, often only 1 MB/s - sometimes even AnonFiles was faster than NoPy... Mega is at 50 to 80 MB/s, sustained. There is no match between the two - at least where I live. NoPy was simply a pain in the ass each time I was forced to use it, and I'm not even speaking of its inability to resume failed downloads properly by itself without a download manager! It was so much annoying that I was forced to offload the download to my NAS... And it wasn't even working properly each time anyway. So I use Mega. I don't even need to offload that, unlike torrents or other slow transfer hosts/protocols.
Using the Mega client is fully transparent, it weights less than 150 MB on hard drive, less than 50 MB of RAM, and virtually NO CPU usage when not downloading. If your machine can't handle that, I wonder how it can handle a Ren'Py game, especially such a big one as LiL...
Using a VPN is perfectly efficient: I could hear that you don't know HOW to do it, or that you don't know which VPN you should use, or ANY other valid reason (including that you can't afford the fee), but claiming for non-efficiency is simply bad faith. And as I said, a VPN has other use cases than bypassing Mega's quotas...
Pay me a seedbox, and I swear that I'll put a torrent on it each time: I don't mind using five minutes of Internet connection to upload a file - I won't even notice it, honestly.
But I won't open up my own NAS to seed it, since most people here will NEVER EVER stay connected to seed it too, and Torrent is a very, very, VERY inefficient protocol when you have only one peer. The best solution would then be a FTP download, but then you'll probably complain about being "forced" to download FileZilla, too...
And I wouldn't open my NAS anyway even with FTP. There is some places on Internet where you should never give an access link to your own machines...
Warning: A decent seedbox WILL be more expensive than a premium Mega account AND a VPN plan... Because you pay for a given disk space AND for a given (monthly, usually) bandwidth. Being forced to wait for one month instead of five hours seems to be a bad choice, as far as I'm concerned, so it requires a medium/high-end seedbox.
A good one starts at 50 EUR / USD monthly, FYI.
End of discussion for me: I gave (once again...) the solution, but there are none so deaf as those who will not listen.
