Emmā¦
For me, my budget is absolutely zero so I have to find creative ways to do things:
Defold - you know, this pretty kewl game engine
Musescore, Leshy SFMaker, and Polyphone (once in a while, LMMS) - music and sound effect generation
Audacity, TwistedWave, Online Convert - sound editing
Hecking MicroSoft Paint - Sprite generation (pixel art, I guess)
Paint Shop Pro 9 and Super Mario Bros. X - Things to do with making clear backgrounds and messing with alpha values that I canāt do in MS Paint
Krita - something I plan on using in the future
Google Docs and .txt documents - documentation and ideas and other funny things
I use a potato computer that has Windows 7 on it. :3
