I think it would have been nice to have a counter of the glowy's collected.  I wasn't sure if I had to collect them all, but I went around and thought I had most of them and then some seemed like they reappeared where I had already collected them.  I wasn't sure if this was a bug or not, but I finally gave up.  I liked the effects and controls.  The intro was neat with the buttons giving instructions, but I was confused on one part because I pressed the buttons and the exit said Go back you haven't read the tutorial so I thought I missed something, but it was because that was visible when you hit the button once.   Great job on your first game jam submission!
