Indeed it does! Thank you for trying it out! In the options menu, there is a setting to adjust the background brightness! You can even set it to 0! I hope the setting helps sorry if it was unclear on the existence of the setting.
OH I had no idea. I just kinda assumed that since this is a game jam game, that the settings would be just SFX/Music (like what many other games have) Now Im glad you actually thought of that
