Finished!!
Oh my gosh. I was able to complete the platforming aspect of the game, balance the difficulty, and add music all in the last hour. In fact I had a pervasive bug where the corners of my platforms were black and not transparent. It was with me for last day and I thought I was going to have to submit without fixing this. Fortunately I found the bug in the last minute of the competition and was able to hotfix it!It's been a really long time since I've finished a PyWeek. I did all of the programming work and my wife did all of the art. We found the music and fonts online free for noncommercial use and since this game is open-source, I think that counts. If you are interested, you can track the development on github @ https://github.com/lukevp/pyweek23. I took a code cut at 0:00 UTC and I am going to do some additional tweaking / code cleanup, but of course this will not be entered into the competition. I wish I had budgeted a bit more time to do some more testing.
