I must say it's a good game with potential to be a great game.
If you don't mind, I have a few suggestions:
1. Make the tool bar at the bottom something you can toggle off/on, it takes up too much space, and the options are redundant as you can do exactly the same through the menu tool provided. I see no reasons to have it there.
2. Improve or change the dialogs after interacting with objects in game. If you interact with an object and get an item from it, interacting with the same object shouldn't say something "oh, let's see if I find something again here" or "no nothing, better luck next time".
It only makes the MC sound like his brain didn't develop, which is weird because the perception you're trying the girls to have of this guy is the one of an impressive and smart guy. His dialogs should be more aligned to his character image, traits, personality and intelligence.
3. If you are looking for a particular object to solve a puzzle that you previously interacted with, once you find that object, the dialog shouldn't say "oh I wonder what this knob door is for?". I mean.... it's like, it's common sense, right? If you know what you're looking for, then after you find it the dialog should be like "okay, finally I found what I need to open the freezer or solve the puzzle, or let's see if I can use this to open the door, etc" instead of a dumb thing such as "oh I wonder what this door knob is for?". Still, it's the same as in point number 2, the dialogs do not reflect the apparent personality and character traits the girls are seeing in the main character.
4. Sam appears in the coffee room right before the freezer puzzle. I can't interact with her at all, but if I go to the changing room, I will have a chance to see her there naked. There is NO consistency with the positions of the girls. This RNG system should be rethought because you're telling a story and knowing that you just saw Sam in a room just to see her magically popping up in a different room breaks the entire "immersion". All you can think of is "ah right, the game is doing a game thing".
5. The music is awesome, it sets the mood, but by default it should be lower volume than 50. Otherwise, it just gets tedious after a while. Or just add more music to the library.
6. Interacting with Objects should give you some sort of feedback, such as when taking pictures of the ghosts, the first thing you should realize is that there's a ghost and that you should take a picture, through a dialog or something, or maybe a previous explanation from Sam. It took me like a whole hour to realize that's what you wanted the player to do. Also, there should be a real reason behind taking these pictures, it just feels like a filler mechanic rather than a thing you are encouraged to do. What do you take picture of ghosts for? Those pictures can't even be accessed through the main menu.
7. The game has issues when you first run it on Windows. The the game window is not centered by default. So, you gotta either manually move it every time you open the game or go to pref → set game to full screen. That's something easy to fix, guys.
8. When you interact with the monitors where you're supposed to see what the cameras captured, it does not show anything. I gather the game is incomplete, but at the very least it shouldn't be an interactive object until there's a reason to interact with it. Maybe the cameras should be used to spy on the girls and know where they're exactly at any given time, or maybe random ghosts should appear there, it could be a tool for learning more about the girls by eavesdropping on their private conversations.
9. When you hide the HUD in the game because you want to fully see the girls during the events when they're naked, if you click anywhere again to un-hide it, the text will skip to the next dialog, which is annoying as you could miss a line or two, and the whole point of this game is the story.
10. The HUD is way too big. The buttons next to the DIALOG box take too much space, there's no need for that. You can replace the button text with icons. However, the 3 options on the top right-hand side of the screen are very well thought and designed. Also, the icon where you can change mouse modes is unnecessarily big, it takes so much space that it becomes annoying when exploring the areas because the HUD simply hides a lot of the image that you're supposed to pay full attention to.
11. Please, add a shortcut to change between mouse modes, like pressing the button Z, tab or something.
12. Add an explanation of what you need to do with the mouse modes. It took 2 hours, for real, 2 hours to figure out that there was a symbol that granted you enough strength to open the garage door. I thought the game was buggy because there were no hints pointing out to that. I thought the lense was just to see through the girls' clothes.
13. Change the "Auto" default speed, nobody reads that fast.
First time I used it I missed part of the story. Also, the "Skip" and "Auto" buttons should NOT remain on after the scene has ended because when you try to interact with another object, it skips through the whole conversation. I see now why the tool bar was added at the bottom of the screen... but, then that's a bad design with the Auto/Skip feature. If you fix the root cause of something, it can lead to disabling another unnecessary thing put in place to fix it such as the tool bar, granting more space to the image to be better viewed by the player.
14. Certain objects are intuitive for their use, such as the Axe in the Loading Room. It could be used to break the glass where the toy is. It could be used to pry open the freezer door, the janitor door, it could even be used to open the garage door. If you have an item that anyone with half a brain would think of using for purposes other than what the game actually needs, then the item should be replaced with something more specific.
I don't know what the Axe is needed for later in the game, but definitely it's counter intuitive to have an Axe within your arms reach and having the game blocking you from using it through a simple dialog. I think this kind of objects should be better thought out. Remove it or make it so that it can't be so easily reached, or let it be an item to solve different problems, as a normal person would.
15. Cadet disappears from the entire mall making it so that the only moment you can see her is in the RNG changing room. That definitely could see some improvement. Have her wandering around in the bathrooms where there's OBVIOS paranormal activity. Or sitting in front of the computers. Her character trait is that she's clumsy as fuck, then she should be somewhere she can't break things like in the Loading Room. Every girl should be always visible by the player. Otherwise she's just like another ghost.
16. In the game menu → girls and ghosts' sections, instead of "blacking out" the remaining girls/ghosts' tiles, their tiles should just be invisible. That way you won't spoil that there's just 1 more girl left to find or that there's only 3 ghosts in the game. The story is the main drive of this game, don't break it or add things that turn the story into a "meh, I knew it" thing. Every section of the story should always be a surprise for the reader, otherwise it becomes boring and predictable.
You don't have good CG, you don't have a good reason behind the girls liking the MC, you don't have a good plot either, so the story right now is an average 5/10. So, focus on the things you guys can work on, if you can't make better sex events where there's actually more than 1 frame per 50 lines of dialog, then focus on making those 50 lines so good that it doesn't matter that the MC character ejaculated after a single frame of a demon touching his dick.
Alright, those are my thoughts on this game. It made me feel frustrated a couple times because it's a game reminding me that it could've been better designed and developed if a bit of common sense was added during its development.
I hope these points I took the time to write can help you better tailor the experience you're trying to create for your players.
Great work, keep it up.
