Not the worst simdate I've seen, but there have been better. There are a couple of things that make it bland:
1. The game is fairly linear. The choices are obvious (until Cecilia confronts you after class the first time; that seemed kind of lose-lose) and inconsequential, leading to an ending that seemed inevitable. This made it more like a moderately interactive anime, rather than a simdate. This, however, may just be because the game is incomplete (it sure feels like it.)
2. A few of the characters seem flat and uninteresting. I barely felt like I was actually in Ichika's shoes, and the NPCs around him didn't do too well to pull me into the story.
On the subject of the characters: only Cecilia seems to have anything of importance in regard to a story. I was honestly looking forward to having a separate story with, say, Charlotte or maybe Houki.
I did, however, think the concept posed at the end was interesting (albeit a little cliche.) I hope to see more, or perhaps a complete version, in the future.
