It's all good!! Take as much time as you want, good things need time to cook well <3 QoL additions are always a nice treat!
Milo is one of the guys I'm curious about (he's also so pretty...), since the mouse archetype is kind of absent when people dabble in animal-based story settings. Quiet, unassuming characters who turn out to be yanderes are such an experience <3 Feels like betrayal if you know the guy for a while lmao. Him being besties with Nox is such a red flag LOL, ain't no way a sane person would willingly be around that cat >.> Also omg another rabbit?? I'm getting so spoilt <3
I WISH I could recommend a similar game to yours, but genuinely there's nothing out there in the ether </3 I've also tried my grubby hands on all sorts of otomes over the years, but they are indeed usually vanilla and unsatisfying when it comes to yanderes. At most we get a few bad endings where we get a wee lil glimpse of all the good stuff we really want lmao. There's of course the Boyfriend to Death variety of games, but idk, I personally don't count them as otomes.
I do hope more people take works like yours as inspiration to create their own dark otome projects in the near future! I am personally hoping to figure out how to create visual novel-style games one day, and while my writing is not the greatest, I would love to add my own little contribution to this genre I've adored for so long <3
