Sorry for my slow reply!
It is super duper hard to motivate yourself to work on stuff like this cos even though it can be fun, a lot of it is pretty tedious so it's kinda difficult to find a balance between working on a project and having fun actually playing games >.<
With me I haven't gone about things in the best way, it'd be ideal to still play stuff and watch anime like you say, but once I got really into my project any time I tried to play a game I wound up just feeling bad that I could be working on my project instead :( So in the end I practically stopped gaming and reading and watching anime altogether! It was good for making project progress but then it feels more like you're just working and not having as much fun anymore xD
I think it's best if you can find a way to divide everything so that you still have the opportunity to make regular progress on a project but still have time set aside to just switch off and relax with other hobbies :3
I think you'll get there in the end, even if it doesn't seem like it at the moment! Sometimes even just doing the tiniest bit of work can give you that spark you need to get fired into action, haha. At the end of the day, stuff like this takes a hell of a lot of time and is a pretty difficult thing to achieve alone. It's doable cos other solo people have managed to release stuff, but when you think about it, most releases come from groups/teams. I hope you do manage to find a way to bring your story to life though :3
I'll be honest, I'm not overly happy with how Palette turned out! Haha. I'm glad I managed to have something finished in time to submit to the jam, but it's not really what I wanted to be, I just didn't have enough time to properly work on it >.<
Hope 2020 is off to a great start for you and good luck with your story!! :3
