my game onky have 87mb its for my university, how i can great permission to upllad more tan 500 files?

You can contact support and ask for the limit to be increased. But if it's a web game, then 87MB and over 1000 files is a lot. Most PCs are going to choke on something that big. Might want to consider a desktop build instead, if it's possible with the engine you're using.

yeah i have a desktop versión and Android versión.. but maybe its posible run online..

you can get more space if you contact support (I had to do it too) but you may want to take this as a sign to optimize your build and make sure it’s as lean as possible (minifiy code, remove redundant assets, utilize sprite sheets, optimize media asset sizes etc...)

The reason I needed so many files was because my game was supporting 3rd party content (mods) and I realized that my game would keep growing, so I decided to load modded assets in externally from a server to save space.
