Pretty accurate. It mostly depends if you play with the guide or not. While the routes themselves are short they intertwine with each other in cool ways e.g. it's easy to accidentally fall into another route or get a bad ending (some choices are pretty vague, if you don't use the guide, then save often).
The artwork is something straight out of Clannad and Kanon era. Seeing the cover alone brings back memories.
It's going to get you to leak bodily fluid one way or another I guess.
