Thanks for the kind words, and glad that you enjoyed it!
I had a Super Firewing 64 (with more levels) fairly far along and was considering selling it for $5 or so, but first I need to find the motivation to continue on it. :-(
I totally understand not being motivated to finish a project. Life is really busy! However, I noticed that there was another comment about a month ago that is positive and I'm sure there are others who have played that would like it. Feed that to your motivation factor. There are people who would play more of this game! At least update the release with more levels if they're ready. :)
