Anyone with some image gen skills/experience and a 16gb GPU can continue the development of this game. The steps to follow would be:
1. Being familiar with a stable diffusion interface, getting all the core concepts and basics down over a few days (Automatic1111, maybe comfyUI)
2. Making a LoRA from the already existing art of the game
3. Finding a good combination of prompts and LoRAs using a model like hassakuXL/Pony Diffusion V6 from civitai, to generate new poses and pictures
4. Ta-da, with enough time spent prompting you'll have cut-ins and scenes, in a very similar style to the original.
5. It may also be possible to make animations from there, it's slightly more complicated using only free and local tools. But luma can be a great solution for that purpose.
Do note that this will take more work and time than most people believe it does. And you will need a precise idea of what you want to create each time, and knowledge to use all the tools you have.
This way, someone with the time, passion and programming skills can take up the torch completely, while staying true to the original art and spirit of the game. This is slightly advanced but possible and doable.
Just a suggestion and keywords to help anyone possibly interested, but afraid that the drawing style would be a dead end.
