Left a similar comment on the itch.io page for this game but to recap:
Found Once In A Lifetime a while back and was really happy with the game and how fun it was to play. Great balance of story arc, character development, and animated content. Discovered Eternum about a week ago and I have to say I'm even more blown away. Absolutely in love with the characters, the development that you've made with them, and it goes without saying but the graphics are absolutely STUNNING! I think it's all these details coming together so harmoniously that make this game so special. It's very rare to have a game so well made that it would be a joy to play even if all the NSFW content was taken out but Eternum manages to easily fall into such a category. Easily my new favorite game of all time and I have nothing but praise to say about it. You have my full support and I can't wait to see what you have next in store for us! Again just really wanted to at least share here how blown away I am by this game. If you are just discovering it here DEFINITELY TRY IT you will find it an absolute joy to play.
Just a small side note here for Caribdis or also open to feedback anyone who may know more about this project but I've been trying to get into developing some basic VN's myself and was really curious about what software and major methods you use to put a project of this quality together. Thus far I've personally been developing models in HS2, looking at developing scene setups in both Blender and Daz3D where I plan to make my animations as well, then finally putting it all together in RenPy. I'm just really curious about what software and methods you are using to develop each individual aspect of this project specifically and how you manage to put it all together into such a well made final product. In terms of software specifically I'm curious what you use for each aspect this project (characters, scenes, animations, etc.) and more specifically how you typically tend to export characters and put scenes together, and most of all how/where you render animations to get them to look so fricking gorgeous (applications, important settings, etc.). All this being said, I understand that part and parcel of making something with this level of quality comes through invaluable knowledge, experience, patience, and practice. Again I'm just trying to learn and get as much knowledge as I can to keep developing my own works so open to feedback from anyone. If you do happen to see this Caribdis I do want to say as well I'm not sure if you are comfortable sharing all these details and if not I completely understand. That being said to you and anyone that may respond all your help and feedback is much appreciated!
Really looking forward to what this game has in store for us next!
