We agree. Sound is also a very important part of a video game, from the background music that sets the mood, to sfx that serve the gameplay as feedback to the player,
Thanks for sharing a little bit of your workflow! We think that is more common to see information and tools to come with some nice visual placeholders at the very least, that it is to find something about creating sounds (not just downloading them from a site)
Also, if someone is interested in sound effects for an 8-bit style game, we've found that https://www.bfxr.net/ is a pretty helpful tool
