I'm pleased to announce the a playable demo of Fireworks Show Creator is now available for Windows!  Version 0.8 is now available from itch.io.  Feedback desired and much appreciated!

Recent improvements:

• Improved timeline GUI to include five separate "tracks" - one for each firework mortar.  When the user adds a shell to the timeline, they can select one or more mortars to fire it from.
• Added a secondary burst color for shells like the Double Peony that explode in two stages.
• Improved explosion graphics.  
• Added pause menu (Hit ESC to pause)
• Added hide/show button to hide timeline while watching a show.
• Bug fixes - lots of bug fixes!
