It isn't clearly specified in the rules and this si the first time I participate in a game jam.
Nope, free music or art can't be used, fonts are an exception.
So, it is not possible to use default sampled instrument sounds in programs like LMMS for creating music? Eg. Piano, violin etc. I have to synthetize all instrument sounds myself? Or record music from real instruments?
Also,You can use sfxr like tool to generate sound effects
