I think you should make a second one, but make it with like at least 4 different people. The length of this is good for 1 character, but this would be such a good game if it were longer with more cases so I can also get to know the succubus we are.
The characters are cute as always. I always love your characters and I want to get to know them more. I wish all your games had a hug or headpatting mode. xD
