I'd say, based on the information, it's simply a matter of prioritizing what you feel is the better work and what you're better at coding/writing/illustrating. Keep in mind we're not too far into the jam where you couldn't start to change the direction of your project if you want to. If you recall the previous yuri-related game jam, a personal favorite of mine created by TeamANPIM was started a week before the original deadline. Although you yourself are working at this alone, I feel if you make changes while you still can, it'll be that much more painless reaching the final goal.
