User blog comment:TinyCastleGuy/Unused Content/@comment-1455034-20140607133023

Because with all the unused content there is in Nitrome games, there will be problems. First off, unused content has a lot of images, and eventually the page will become unreadable and it will lag the browser. Second, the page will reach almost a MB, and most people will be unable to view the page.

I don't really see how it takes up space with "minor details". Sure, there is unused content in the form of unused text (which can get pretty boring) and unused weird things (which also get pretty boring as well), but then there are some genuine interesting unused content.

For example, Mega Mash has many, many unused enemies and hazards, Test Subject Complete has interesting early bits of the story, and Toxic has weird things pushed off screen.
