I really like this game! The character designs are cute (and a bit creepy as well, in the best way), and I'm very interested in the story. I'm also curious to see more of the Jester who was mentioned a couple of times (I know that one won't be a romanceable character, but I'd still like to see them since they were referenced)!
I like the creepy aura that's created in some of the moments with the weird eyes and sounds and things. And I also love how Pierrot is illustrated when he gets creepy and passionate about the main character - the heart eyes especially.
I will say there was a slight error in the English version at one point with the use of a feminine term in the 3rd person ("her") if I recall correctly, so I'm assuming that's a holdover from an original draft or script or something. Just a small error I noticed, but it didn't detract from the game as a whole.
Anyway, I would love to see more of this! Pierrot is my favorite right now, but I'm curious about Harlequin for sure. Can't wait!
