Thank you very much for the tips, it's really hard to think about these details when you're doing everything alone, especially since it's my first time doing something in RPG Maker.
No problem. Like I said, I very much appreciate you making a honest effort at making a game like this (even if harem isn't really my thing.)
Solo dev-ing is definitely tough, especially at your first game. What I find/hear helps most is to compartmentalize every aspect of your storyboard for the day. Stuff like making a checklist consisting of all the things you want to look into on a single aspect, like writing, mapping, drawing, ect. That way you don't get overworked by trying to focus on every aspect of the game all at once.
Rest/research days are also good, where you play/watch videos of other games (not necessarily only RPGMaker games, since the general idea carry over to multiple engines, but with mapping/titlesetting it would probably be more useful) and see how they do certain things. It doesn't even need to be just games, as reading/watching unrelated things can spark new ideas for your projects.
Everything is a slow process, and I wish you well on you well on your project. I hope my advice doesn't feel too unsolicited or overbearing.
