Hi there! Great to know you are having fun with Caliross! ^_^
Yes, in theory I can use Mega or GD (and I actually already use Mega for the patrons-only releases), however having the files hosted here is more convenient, and generally reducing the size isn't a bad thing, so there is that.
In theory, you can get approved by itch for an increase in storage, but yeah, I figure it's easier for some to host the files externally without going through the process.
The process might not be super troublesome, but you have to contact the guys running the website, they ask you to make sure you are following best procedures to keep the size small, and then if you still want it, they'll get back to you after evaluating your project. Since I didn't go all the way through, I am unsure what requirements they have in mind, but I figured that since I don't sell the game here, it's probably not fair to ask for more space anyway.
