Onboard Tactics- outplayed

You can make the pieces fly by doing whites move yourself at the same time they do it. Then you cant move any more pieces (glitch), and you need to restart it. After you restarted it, a piece missing on your board should fly back to its place. =D Flying pieces

And your page up and down blue bar thingy should shrink, because your piece has teleported somewhere far down or up and far left or right. Try it here, after Kxf7, go to the knight on d3 and drag it to e4 and let go at the time the puzzle would.

Edit: you dont actually need to do that. Just hold the piece that is supposed to move for white. Try holding the bishop BEFORE THE PUZZLE MOVES IT. Then it glitches up and you press restart o.O
