I'm really glad you liked Shimil so much! I spent a whole month before the yan jam crafting him and his backstory, and I feel really proud of how he turned out.
I remember about half-way through development I realized how many bad endings there were for him and felt bad for him, but at that point it was too late to add or remove anything to make time to make another good ending.
But I would like to imagine in some timeline he's met someone who truly understands him and make him happy.
