Hello! you need to go over platforms in special way, you need to "press" them in order they appear. Be careful and do not push the floor panels in wrong order, go exatly in the centre of the each panel in order not to push another) For first power station and than for second. After it you need to push both panels on the door if they are blue and go out.
About image size, yep I know there are problems, because I didn`t work with HTML5 ever before, so did`nt have much time to figure it ot.
Thank you for your comment, hope you will pass the room, if you give my game one more try!
