Thank you so much for your comment, I really appreciate it!!
Grimm did have a super subtle blush if you chose to flirt at the very last option (saying you got to see him smile; the dialogue was "got him!") but since he disappears if you click right away, it might not have been super visible hahaha. I'll consider bumping up the visibility on it so it's a bit more clear.
Flirting with all of them is totally the recommended path ;) we're all thirsty here hehehe.
Absolutely re: music, I would have loved to add more but lack of time/resources to hire a composer for a full sound track meant I didn't have time to focus on that, but it's something I'm def going to be aware of for future games. If Halloween Scrooge gets some traction I'm considering making a sequel otome/amare game expanding on this world a bit with routes for these 3.
Thank you for playing and I'm glad you enjoyed it!!
