Pen platformer

My first game, don't expect much xP:
Edit: Jumping on mobile doesn't seem to work in the iframe... weird

Nice but you can easily cheat by dragging the player sprite with your mouse.

Oh- fixed that ._.
I did this, hope it works:
set [draggable? v] to < false::operators>

Almost. If I try to hold it and drag it swiftly, the player sprite will fall. But I can still hold it. Probably a Snap! bug.

Am I supposed to not be able to jump on the second level?
Edit: it works in the editor, but not in the iframe.

Please add arrow key controls. Also, jumping doesn't work for me at all
edit: oh you use space.

Please also write instructions.
