That's really strange. I only use copyright-free sound effects, mostly from Pixabay, and I don't even remember if I have a raindrop sound in the game.
Could you tell me exactly where in the game this happens? If you can tell me the specific location, I'll check it.
Also, a lot of streamers and YouTubers have played the game before, and this is the first time I've heard of this issue. If there is a problem with one of the sounds, I'll definitely look into it and replace it.
Ok I just check on video number 16 that I made and the sounds comes from this area it said from 01:03 to 02:26 then 02:14 to 02:26 this is the area from the video also close to the radio
