This notice must be kept for any source code releases you do in turn. We don’t require prominent placement in your game credits. Just tuck this notice away in your EULA or other legal documentation (look at the Unity EULA for an example of a bunch of 3rd-party library licenses).
If you feel we’ve helped you out quite a bit, a more prominent thanks/mention/Blurst link would be appreciated, but it isn’t required.
