Include a submenu for the asset library which allows you to more easily navigate to content.
Open the asset library for vetted user submission. (New drop down > upload an asset)
assets for demo games/tutorials
e.g. brick breaker could be in games > brick breaker > then split assets into own folders (sounds // music // sprites > backgrounds // paddles // bricks // powerups)
Great suggestions. I've added a sidebar menu but I think the whole design of this page needs a review especially if more assets are added. I like the suggestions of assets for demo games and tutorials too!
