The rules should have the answer you're looking for!
1. Tag your submissions appropriately! If there is violence, substance abuse, mature themes or other such things, please list the types of content within it. Not respecting this rule will count against your submission in judging!
2. We respectfully request that all submissions be made without explicit sexual content. We won't complain if you change it after the jam.
3. Submissions containing depictions of suicide or self-harm will be disqualified and removed. Text, whether in-game or in the files of the submission, containing instructions, encouragement of, or statement of intent of suicide or self-harm are similarly disqualified.
So according to rule 1, as long as you tag it properly, it shouldn't be a problem.
