I don't know what is the origin and copyright status of the built-in sound effects in the MESH:Hero Hearts, so I do not know if it should be included in the Free Hero Mesh. I also looked at the OpenGameArt; they have sound effects there but is not quite right and is a higher quality than I wanted (I wanted a lower quality and not too long duration, that will not take up too much disk space if stored as WAV format).
Also I wanted that if someone might make logo of Free Hero Mesh (there might be more than one and then we can see which one is good), which is a project which does not currently have a logo.
