Hello Daraus, hope you're doing just fine! This is such a great game, I really enjoyed it a lot. Really looking forward for the future of the game, (looking forward to finally date the teacher), I actually have some ideas to share.
1. GIRLS CHANGING LOCATION
Currently there are three locations that are not used as much as the clubroom: namely; Swimming Pool,, Coffee Shop, Clothes Shop.
So I think instead of only interacting with the girls on the Club Room, we can find them on different locations other than the Club Room, under specific conditions or triggers (check 1a, 1c and 1c for the condition and triggers I've come up with)
1a. Condition: Equipping specific outfit = For example, if Monika is wearing the "Casual" outfit, we can find her at the Coffee Shop, if she's wearing "Event" she will be at the Clothes Shop, if she's wearing "Bikini" she is at the School Pool.
This will be a condition that can be set by the players, by equipping a certain outfit, which on the next "day" will take effect, causing the girls to be at the area that is equal to the outfit (e.g. Bikini = School Pool).
1b. New Possibilities = Since we will be able to talk/interact with the girls on different locations, this opens a lot of possible endings for the "day".
( Or can be the usual interactions but with different outcomes and a different location. )
For example, the 'Spend Time', 'Gift Her' and 'Change Clothes' have the same function across all locations. 'Personal Sexual Favors' can be the same, but the H-Scenes will have different areas depending on the location (Coffee Shop > Shop's Bathroom, Clothes Shop > Fitting Room, School Pool > Changing Room). 'Public Sexual Favors' can also have a new outcome per location, 'Ask on a date' will play almost the same but with different scenarios per location, also this option might be not available at the Swimming Pool (cause how to date there?)... and importantly just like in the current game, if a specific conditions are checked, a good ending at our house will happen later that "day", this is equals to new H-Scenes at our room ( ͡° ͜ʖ ͡°).
1c. Condition: Girls Status = This can also be used so the game can automatically change the girls location. For example if the Girl's status is "Angry" they will be placed at a random location other than the Club Room. This mechanic will add a fine and somewhat realistic detail. They'll avoid you when they are angry, and they might be waiting for you at the girls bathroom when they are horny and have a higher Lust than Love stat (new interactions when they are at the bathroom?).
2. NEW OPTION WHEN SPYING
If I'm right, when we gift the girls with a dildo but not have H-Scenes with them that day, later that day when we spy on them we'll be able to see them masturbate (where's the dildo tho?). When this happens a dialog "I need to fuck her soon...", what if we add two options after this line, "Fuck Her", "Leave". I mean, currently, the MC can capitalize on this scenario right?
2a. Getting caught = What if we can get caught by the girls spying on them and jerking off of them? This can open new routes and possibilities for the player, or simply affect the girls stats and mood. My idea here is that if we recently caught the girl masturbating but choose to leave (as like in the game), the next night when we spy on the same girl, the game will force us to chose the "Jerk Off" option which will result to us getting caught, and the outcome is determined by the girls mood. If she's Angry and her Lust stat is higher that her Love stat, she will offer the MC services. If she's Angry but her Lust stat is lower than her Love stat, will just ask the MC to leave. If she's Horny... boom H-Scene.
3. SPEED CONTROL ON H-SCENES
This could be a simple but really great addition to the game.
3a. Gallery for H-Scenes = The good old collection section of the game where we can watch unlocked H-Scenes, this will also help the player as it can show the player how many more H-Scenes they haven't seen yet.
That's all for now, thank you so much for this amazing game! Looking forward for future updates, and I hope you can consider some of my suggestions hehe.
