Requires Mouse is a very abstract puzzle game. Left-click to do things; right-click to restart a level.

This is a quite-alpha version; it has only 16 levels, and no save-game mechanism. Fortunately, once you understand how a puzzle works, it's pretty easy to do it again quickly.

I've gotten some useful feedback about this little thing; I think I know what I want to do with it next. If you're interested, here's the source code.
