1. Actually tracking the children will complicate things immensely. For now, they will be some abstract figures in a nursery but maybe in the future I'll develop the idea further.
2. I'm a one man show: I code, I write all the story and dialogs and I do all the art. Animation is currently not something I plan on adding because I'm afraid it will consume too much of my time. On the longer term, yes. I do want to add some but since I strive to have everything in the game high quality, I don't want to half ass it. I do have an assistant coder (you'll see the cool new UI soon) on pay, but integrating an animator seems much more complicated to me.
3. Subscribestar, not Patreon. The perverted content I put into the game would get my kicked and banned from Patreon in a few minutes.
