This log is very interesting. The methodology behind asking yourself "what does the game's current state fails to do ?" is a very healthy question, and while it's hard to judge without playing the game, it seems like you are capable of being honest with yourself on it - which might be the hardest part.
It is something that has to be asked in the development of anything, especially a game, and your answer to it - making S:SD and Sap two different projects - is very interesting. This makes me want to see the game even more !
Also, actually splitting the dev into two projects is an hard decision, and I admire how confident you seem of this choice. It will certainly be for the best.
Still reading all your logs, actually login in Itch.io just to read these every 3 days or so.
