Thank you very much for the feedback and kind words! :)
Yes, looking back I would absolutely add a second tutorial level, that explains the proximity buttons that are hidden in hard-to-reach places. That was an oversight and I only realised it should have been done right as the jam ended! And I also agree on the volume, will definitely look into adding volume controls going forward with our projects. Also on the physics and scaling, I also agree, with some more time to polish, it would have been great to refine the scaling a little more and also make the objects a little less excitable haha!
Thanks again!
