Really digging the game on a conceptual level. I know there's probably a million things on your roadmap when it comes to improving and building on the game. I'd like to share what I would enjoy seeing or seeing more of:
1) I would like it if there was more dialogue. Particularly I would enjoy seeing dialogue change as girls became more corrupted. As is there is very little change between the character first being introduced and the character being fully corrupted (or rather, as corrupted as the current build allows).
2) I disagree with the previous feedback and would like it if there was MORE of a penalty for being discovered. I think the attention/detection stat is fine as is but I would like it if, when discovered, you were forced to remove the HALO and lost battery charge or something so you couldn't keep corrupting your target. In essence, I would like to prevent players from being able to just mash 'fuck her' in public and then get a girl fully corrupted instantly while only taking ~30% detection. More exhibitionist type possibilities should open up with either very specific characters (increase exp or lust gain when this specific character is discovered or something) or through perks you equip to your slots. To help players with this increase in difficulty:
3) I would like it if there was more using the girls you have already corrupted to help you get new girls. The principal is the easiest character to corrupt so I like the idea of using her as a starting point and then being able to call new girls to her office or something. Make it so that girls above a certain level of corruption don't get suspicious when you are corrupting someone else so you can corrupt Zahra even while Ava is still in the cafe. Make it so that Lisa at sufficient corruption has the class try on a HALO or something and just slightly corrupts all of the students without them knowing. I dunno, stuff like that, more complex story threads or plots in which focusing on a single target makes it meaningfully easier to then expand your harem.
That's really just about all I want right now. The game is obviously very early but if it had a bit more depth to it (both depth with individual characters having more to say/do and narrative depth by introducing different 'paths' or methods of using one girl to get more girls) it would be really good. I personally would rather see the existing harem fleshed out and made to feel really satisfying to enslave all of them before adding new locations/characters.
Anyway, I get that you have your own goals and ideas moving forward so of course disregard any of my feedback as you want. Hopefully some of this is of use to you.
