Hey, sorry for the late reply!
The bundle comes with a Royalty-Free Commercial License, so yes, you're fully covered for commercial game projects. You can use the sounds in any game you release, no royalties or extra fees involved. The only restrictions are redistribution and reselling the files as standalone assets. Crediting us is not required, but much appreciated <3
I'll be sure to include a license file in the project. Thanks for pointing that out.
Hope it helps your project. Feel free to message us if you need any custom music and sounds or if you have any questions!
