Ludum Dare is a great place to know more tools for game development, so I’d like to share the tools I used to make Micro World.

Programming:

Flixel – Open source game-making library for ActionScript 3.

FlashDevelop – Open source code editor. Supports ActionScript (2 and 3) and haXe .

Graphics:

GraphicsGale – Animation graphic editor. Good for pixel art.

Music:

Guitar Pro. Tabulature editor software. I used it to write the song and export it to MIDI.

GXSCC – Automatically converts a MIDI to 8-bit chiptune. Just drag and drop your MIDI to this window, then click Authoring to export it.

Sound:

Bfxr – Generates manipulable sound effects with 8-bit style.

Free Audio Converter – I used it to convert WAV to MP3.
