"If you're smart enough or Google enough, though, you'll probably find out you can just reinstall Windows and restore a backup from your harddrive and ruin the entire point once again because you're a teary-eyed little child, but the upgraded challenge in the metagame would definitely set UNDERTALE apart from video games."

Actually, how about no you can't? If you reinstall Windows, you'll have to reinstall Undertale to play it. And the file'll be backed up on Steam.. *grin*
