as someone who also either stops doing something or the joy goes out of it by saying okay im going to focus on this and work on it. take time I would say dont post updates to the rewrite until you are almost finished or if you feel like you still possibly wont finish it at that point to wait until finished.
Because you said you are rewriting will you have some people comment: "is it still being worked on" ignore those. all it will do is add pressure to you. dont worry about letting people down. if you update a lot and get more people interested, and get burned out and not finish that will let down people more.
SO INSTEAD just work on it for fun when you feel like it. dont update the game on here just focus on having fun and writing the story. And one day whether a few months or years later being like surprise here is the full story/game. (I also havent shared stories or interactive stories yet because I also get burned out or just cant figure out what to do next and I dont want to let others down)
Also see what works best for you writing wise. I personally notice trying to get ideas or writing on my laptop is a lot harder than writing ideas that pop into my head on my phone. And if i have a lot for an idea i write it on paper first and then later add it to my laptop. I just seem to get more ideas when i just have paper in front of me versus if its a laptop.
Lots of love your way, take your time, have fun and dont worry about when you finish it. :)
