"Oh, here's an interesting concept. myshmup.com is a site which allows you to play lots of little bullet hell-like shoot-them-ups, but also to remix them."

"You have base levels with different enemies and scenery elements that you can change through an editor. It's simple, but it's fast, and it allows for example to do team building in the office."
