How do I move Juni's sprite in the starter tile?

When you start a new level you're given Juni standing on some pipes with the exit below. While I'm able to remove the tiles easily, I don't know how to actually move Juni to a place I'd like. There's nothing in the FAQ or the PDF tutorial I saw that addressed this, though I may have missed it. Could someone enlighten me?

there's a button called "set start position", which lets you do that and choose the powerups you begin with.

There's a button below the editing screen that says "set start pos." where you can set the starting position and powerups. Click it and put juni where you want her to start the level at.

Words are very boring, don't you agree?
