It's amazing that you got this set up the way you did. I don't really know anything about Devil Survivor, but my SMT-savvier friend told me that this was quite an accurate recreation in several aspects. However, as someone who doesn't really understand the mechanics, it was quite overwhelming, especially due to having 6 different tamers who all had different attacks and party members. But I got the impression that this was more of a proof of concept of an engine and mechanics than a game. And as a recreation of Devil survivor, this is quite impressive. Hope you'll use this as a foundation for something, because it's a promising start.
