After completing two thorough playthroughs I have a little feedback:
+ Love the character design, nice variation in face and body types and love the casual sexy look to the clothing and poses in particular. Top notch stuff here.
+ Fresh setting and story. Great job at breaking away from the norm school/work/city/beach/park/restaurant over used cliches.
+ Great sexy scenes with a lot of anticipation and excitement behind the scenarios.
- A few render minor render issues: maggies eyes in the doctors scene don't have the right texture, sharp shadows in the sub scene on body parts are somewhat distracting even if realistic.
- Lack of romancing seems odd, but possibly understandable given the characters
- Lack of choice/branching can lead to some scenes feeling like they just happen without kean earning it. I understand that there are ways to both fail, pass and pass 'with extra credit', but aside from the spa scene
there just seems to be a pass or fail story ark. This can lead to scenes feeling a bit out of place if you miss some things, rather than having a toned down scene for those who miss some things. I appreciate that this is more of a graphic novel than a game and being broken up into parts means transferring different outcomes between parts would be a problem, but none the less it made it less of a natural experience for me.
As for characters I want to see more story/scenes with! Cassandra and Kaori are my top two. I still think I like Maggie the best but it seems like she will be covered by Keans story. Lucky me, I guess.
Again, great work. I'm trying to be as honest and constructive as possible here because your games are the closest thing out there to what I would make myself if I could.
