I just wanted to say that I wished I played it sooner. This game is just so fun, so charming and I love all of the characters. Iolanthe herself is a great MC, I love her to bits.
I enjoyed all of the routes and If I had to rank them based on how much I enjoyed them it wouls be like this:
Fredericks's route was just so sweet, I really loved Iolanthe and Frederick's close relationship in the game, they had natural chemistry and interactions that I enjoyed regardless of which route you're on. I was initially worried about his route being awkward as a romantic route but I was surprised to find myself loving their route, how natural it felt and understood why both would or has fallen for eachother. I kinda wished it was more explict but I guess it's fine.
Leopond another character who's interactions with Iolanthe were also great to watch. Leopond is such a charming character, I thought that I would find him boring but I was proven wrong.
Charllotte is sweet, I liked that in her route, she grows as a person and becomes more confident and independent despite the small amount of time interacting with Iolanthe. All Charlotte needed was someone to not chelter her, talk her down and beleive in her, Their ending is one of my favourites. To be honest I also didn't think much of Charlotte as a love interest based on my 1st impression of her but she surprised me.
I would go on about what I loved with each route but i'll just stop with my favourite 3.
But yes, I really loved this game and the fact that it's confirmed to be getting a sequel just makes me happy since all endings with each routes would be great with a continuation (especially Leopond, Sofia and Frederick's endings) and since the plot for the sequel seems to be deeper I'm sure it'll be just as good or better than this game. Overall, I hope for continued success for this game and any game you make in the future!
