Hey Anvith! Sorry for the slow reply, we haven't been checking the forums as much lately due to "down-time."
I'd love to maybe let you test some of our software in the future, feel free to email us at email@example.com.
As for NNGINE, it's really not ready for use outside of our controlled environment yet. We still have to custom-make a lot of the tools that we use in our games - however, once We Shall Wake's final version releases, we'll begin seriously looking into making it publicly available for anyone to use.
