I need to get this effects for my game as soon as possible to polish my game (or other people want get some free sound effect ) , thanks :D .
You can usually ask people on Twitter or Facebook if they can collaborate with you. That's because I also don't know how to make good audio effects, so I just sent some tweets to people if they can help. All the best for the game jam!
Thanks a lot, I have found something yesterday, https://www.zapsplat.com/sound-effect-categories/ .
It's a good HD sound effect, free to use for game, so thx for your answer ;D.
