Organization help!

We have this super awkward closet and we need to do something to make it more functional. The basement stairs are on the other side, so it has it’s own steps of sorts within it. The door is weirdly narrow, but that’s not changing due to the location of studs and supports. It is also an access point to the attic space, but not a useable one due to how insulation was blown in.

Currently it is home to games, puzzles, and shoes, and as you can see it’s a mess. Is there something that doesn’t involve major work (nothing with Sheetrock) that we could do to make this a functional space? What would you do?
