The storyline is pretty linear but it shouldn't matter much as you're playing this for the sex animations and images. A lot of work has gone into the visuals. Game has possession, mainly M+f sex, and some body modifications so far.
You're off to another great start. I enjoyed your other game Ordinary Day and this is a lot of fun as well so far.
I'll echo the other reviewer that the steps could use a bit more guidance. I also had trouble progressing without the walkthough.
I liked what's there already. I'd suggest changing the order of events that you don't have to leave the park to go to the beach and back because that got me stuck the first time without the walkthrough. I liked the idea with the pills a lot, would like to see more of that, and all the things in store as the story progresses. Looking forward to it!
