Thanks! Yeah it could use a lot more explaining and tuning. The goal is to progress to the end of the level by swinging and attaching objects to yourself. One problem is our camera is too zoomed in and the level too spaced out to see some things. One thing you must have missed at the spot you got stuck were a bunch of balloons to your right (the camera was too zoomed in to see). If you click on these you can attach them to yourself so you can float. Later on there are more objects you can attach to yourself that weigh you down or let you propel yourself.
More tutorial text and some tuning of the level and camera would certainly help. Thanks for the feedback!
