So, first of all, thank you for your feedback!
Yes, the beginning was very much inspired by the DxD anime, of course it will change over time.
And yes, there haven't been any updates because we are in a very strange and heavy period, between projects we are developing slowly and some pretty heavy personal problems, it's hard for us to move forward quickly.
But the project has not been abandoned, when there is a chance and the situation becomes lighter, we will release a new update sending the game forward. We will publish a Dev Log where we will say the same thing in this comment, just for clarity.
Thanks again for the comment, it is very important to us!
