There is much to praise in "Sunshine Love." The art and renders are well done, the animations are minimal, but fluid, and the broad story is compelling enough. Unfortunately, the game suffers from many small flaws, which make my final review 3 stars instead of 4 or even 5.
The biggest flaw is the poor dialogue. Characters spend a lot of time talking about things completely superfluous to the story or themselves. When talking about relationships, their feelings for each other, or anything substantive to the plot, it tends to be very juvenile.
This brings me to the second flaw, which is that the MC and several other characters act like adolescents. For example, in version 7 the MC finally has an opportunity to have sex with his "friend's" mom or aunt, depending on which path you chose. Despite having made out a few times and seeing her naked, the MC still has an internal monologue asking if she has lewd intentions. Of course she does, you nitwit!
On the plus side, I really enjoy the dialogue that happens during the lewd scenes. The MC is not a sadist (I know it's a kink some people like, but I hate games with an MC who talks to his sexual partners like a serial killer) and the back and forth is good ol' fashioned dirty talk.
I also don't get the "tasks" the game provides regarding the hotel. The game throws up these big splashy graphics whenever a new task is added to our checklist, but given that the MC later completes them automatically, I get no satisfaction or feeling of accomplishment from it. It seems that the dev wants players to feel like they're making progress in something without having free roams or sandbox-type events, but it doesn't work, at least not for me.
