Thank you very much for the detailed look at the game. A lot of the challenges you described were the ones I was worried about. We were probably going to keep tweaking it a bit after the judging for the GMTK game jam is over. For orb control I was experimenting with its AI and probably went a little too complicated for our first time out. I tried a third party library for it and I didn't understand it enough to use it well. I think I do want to try an easier mechanic for it. I also agree the level design could take a little more time.
All in all it was a lot of fun to work on and your comment will be very helpful. Thank you for taking the time to write it.
