Through Time is a dating/romance/slice of life CYOA with a number of endings and potential romantic paths.
It includes some 'puzzles' of the date sim genre (which activity do you do first on your date? how do you respond when a person you are interested in asks about your feelings?) and the puzzles are clued well, so you can get a satisfactory result an make choices that feel in-character with the role as you see it.
The writing could use some polish, but after a first play-through, you'll be doing more skimming than in-depth reading; the writing isn't bad. It just would be stronger with some editing and paring down of some sections and a few over-wrought passages.
Overall, this is a strong entry from (I believe) a first-time IF author, and I'd love to see more of their work. I'd recommend this game to new players as well; it provides minor but non-frustrating challenges.
