For my LD29 entry, I used a community fork of Flixel (https://github.com/FlixelCommunity/flixel) and a community fork of Flixel Power Tools (https://github.com/FlixelCommunity/Flixel-Power-Tools).

I also used the freeware, commercial use allowed font PF Tempesta Seven (http://www.fontspace.com/yusuke-kamiyamane/pf-tempesta-seven).

For text editing, I not only used FlashDevelop, which is a nice IDE useful for AS3 development, but also GVIM, which is a free, open-source editor (http://www.vim.org/).
