TLDR: This short VN hits the sex quickly and has a good variety of sex activities, but is held back by boring writing and non-animated scenes despite using Illusion as the renderer. If you enjoy Illusion/Koikatsu visuals A Day by the Sea does not add anything significant to that starting point.
Breakdown:
+ There is a healthy variety of sex activities, including (semi-consentual?) sleep sex, consentual sex, and rape.
- The skeletal and disjointed story is forgivable as an excuse for sex scenes. Unfortunately the writing during those scenes consists of brief and uninteresting description of physical events. Good writing should paint colorful characters, interesting situations, and vivid feelings for the audience. This does not qualify.
- The main girl's face is comical or horrifying, maybe both.
Conclusion: Overall this is the game equivalent of a slice of white bread with a square of butter: Nothing wrong with it, but not interesting or high quality.
