Hi smallmak,
The license terms can be found at the bottom of each of our asset's description. The game can be personal or commercial, it doesn't matter.
Here's the license term:
- 1 purchase license per game
- Do not redistribute the music/SFXs as a part of different multimedia templates or include them as part of your game's OST!
You don't need to credit us if you buy the music :)
Hope that answers your question and let me know if you have more questions.
