Hi!
I'm glad you liked the game and of course you can stream the game if you desire to or make youtube videos.
Regarding the sound effects and music, the music is either free to use or AI-generated, and the sound effects are all either hand-made or taken from (freesound.org) under a CC-0 license. (which means free use)
More credit information is found in the game, If you need further assistance, you can email me at
