I asked it to make a game where you place movies on a time line by dragging the movie poster.

Instead of the movie poster, it decided on its own to use icons that represent the movie instead (a pill represents Matrix, a gun Goodfellas etc.). I was surprised by its creativity to get around any copyright issues.

Doesn't seem to work for me on desktop chrome or firefox (linux), dragging the movie does nothing.

It works for me (desktop chrome on mac). There are some glitches sometimes when the movies start spanning more than one row.

The initial movie needs to be dragged on the thin white line (not exactly good ux). Perhaps it's not visible?

Also, if you have dragged the first movie and place the second movie incorrectly, it will be placed back in the "stack"

Doesn't seem to work on mobile (Safari).
