For the next update, you'll have to tough it out. The one after that, I'm switching it to "Part 2" so the size will go back to a few hundred MB
The game is under 5GB, if you can't get it on mega, it's because you downloaded something else first. You can use a download manager or VPN to get it from mega or you can download it from gofile, the links are on patreon/SS.
There are no costs at all. The game is free and you're free to decide whether you want to donate or not.
The next version, V0.15, will be over 5GB, that's what I meant by tough it out. For V0.16, I'll be switching to a new version of the game so it'll be about 250MB.
buddy how mega works is it allows you to download 5gb per day. If mega doesn't allow you to download it then you've probably downloading something else using mega within 24 hours. This update is 4.9gb which doesn't exceed that max download threshold so maybe you should calm down and not attack someone who literally gives his game out for free.
