Hello, Thank you for trying out the game, glad to hear that you are enjoying your time playing it.
Thank you for your feedback!.
The game still in its early stage!. adding sound will definitely come someday!,
but as of right know, it is not essential, there are other things needs to be added/fixed/balanced.
once the game is stable, other things such as sounds, maybe seasonal events, and so on.. will be added!
If you have any other feedback, found a bug, or a cool idea, please let me know :).
