Just checked this out and I enjoyed it a lot! First of all, I really love the character designs. They're all so fun and creative; I especially love Folly's spade-shaped skirt and Abriel's wing hair. Abriel's outfit is kind of Aikatsu-core too, which is very cute! Love the bunny socks too!
The character sprites are so lively, they have a lot of poses and emotes. They're all used very well too! The backgrounds are less detailed but it fits the Wonderland theme, and I think it all looks very cohesive.
I will say I think the UI isn't the best. The sprites + bgs are both very nice, but I think the very thick outline of the textbox and the font chosen make the presentation look 'cheaper' than it is. If the UI looked a bit sleeker and simpler it would make it look better. Maybe this kind of layout would work, if the colours were adjusted accordingly?

I also think the text is a bit hard to read because of the font, so going for a more simple sans serif font might work.
As for the story and the characters, I think this is pretty interesting! The writing style itself is nice and engaging, and things unfold at a pretty fast pace. The choices have obvious consequences (unlike a lot of VNs which will give you seemingly important choices but railroad you onto one path), so it'll be fun seeing how much branching and variation there is in the finished product.
Also Abriel is very cute! I like her a lot!
Good luck with the rest of the project; I hope it goes well!
Thank you for sharing your thoughts on duplicity loop! Since the VN is still in development, feedback helps us make it better. We'll definitely take it into consideration (we should absolutely have a simpler sans-serif font available for general accessibility, so we've already started working on that!).
