Ok first of all, thanks a lot for your feedback.
Before I go a little deeper into it all, I feel I need to explain something first. With some choices it comes down to this: There isn't really much change other than a little dialogue difference. Though the game counts points in the background depending on the choice made, no matter what, which is supposed to allow or prevent the player from certain actions in future chapters.
Having said that, I've had a look into the points you made and I do have to agree with you to some extend. The peeking at Lily scene wasn't really handled all too well. I've corrected that to what I now feel is a little more suitable so the player now can see that there's a difference.
Same goes for Hitomi's pool scene. You were right that it wasn't clear for the player that there is a difference, so I've added an additional render. So now it should work out better.
The problem with the grabbing Megan's butt scene, i couldn't really recreate. If you choose 'grab it' the game counts +1 point for Megan and gives you an additional scene with dialogue. If you choose 'don't ruin the moment' the game counts no points and skips that scene. Both choices should then end in the same scene.
In the scene at Lily's cafe the MC says 'LILY?! You're working in this cafe?' Not '...in a cafe?' It's supposed to express his surprise that it's actually this cafe they're in, she's working at, not a cafe in general. But I've put the word 'THIS' in caps now to hopefully make it a little clearer.
And last but not least, the reason why the MC acts surprised when Lily tells him stuff while sober that she already told him being drunk is that Lily can't remember anything of what she told him when she was drunk so it's basically all new to her. So he also acts like it's more or less new to him to show a little more compassion. Sure, he coud've said something like 'I know all that already Lily, you told me when you were lying in my bed piss ass drunk....' but that would've made Lily feel bad and there wouldn't have been too much feeling in that scene as well :-)
So I hope I could clear up some things. Don't get me wrong, I totally appreciate the feedback you're giving and you were totally right with some points. I tried to correct these parts so it all works out a little better. So when chapter 6 will be released these things will be changed. But I hope I could also explain my intentions behind some stuff a little better :-) But I'll do my best to improve on things in the future.
