Hey Hapi! Glad it's working a bit better for you now, I personally only use Gemini 3.8 Flash because the speed and quality is totally worth the price to me. If you don't mind me asking, why aren't you able to create an API key? You should be able to sign up and create one for free as long as you have a Google account... I'm assuming it's something like it's not available in your country?
Anyways, I don't mean to pry. For your suggestions:
1. For background generation, you can generate (or find) images outside of the game first. Then, go into the Edit Character modal and click the folder icon under the name. Place them in the character's folder as room_day.png and room_night.png next to character.json. I actually just tested this and it works great!
2. Manual save management is on the list for development. But rewind is already in the game for next update! Stay tuned
3. In the next update, you'll be able to do things like edit the returned response, insert a new action at any point in the reply, and edit character memories. Stay tuned! Allowing system prompt editing is also an interesting idea, definitely considering this. Sorry to hear about that Gemini bug, you can abort the prompt by loading the last autosave or returning to the main menu during generation.
