I have to slow down development on this game. It is very emotionally draining. But I think it is really giving me the benefit I was after. For the purposes of the jam I am going to focus on the introduction and ending sequences and one third of the initially-planned content.
This isn't too bad. I initially knew that the content I had mapped out was too much. I do eventually need to finish it all for my own reasons. But I want to try to ship something that approaches a complete state for the jam. This is very important to me because I haven't finished a game in over 10 years :)
