That's a kind of a problem with the game itself, you don't have a goal stimulating you to see everything. It gets too repetitive, it's repulsive when you have to attempt tens of walkthroughs just to see alternating scenes.it's the equivalent of having a progress bar on The Witcher 3 unique dialogs
it distracts you from actually being able to immerse yourself into what's happening, as you're constantly thinking of finding all the scenes and events instead of immersing in....getting railed on by a giant cock
Gallery was giving at least certain people a small reward for finding a scene. The sense of “I'm not doing same thing all over again, I'm gradually adding new scenes to my collection». Now it's gone, and you don't even feel like you're good that you found something.
If the game had a strong plot, it would at least motivate you to look for scenes because they're giving you some new stories. But the game is more of a big collection of short stories that are independent and not great themselves, they ONLY get interesting when they explain you the hentai scene.
The game could also have more diverse mechanics. I remember the Lust Doll game, it rewards you with new spells that actually give you some absolutely unique effects when you reach some part pf a story. Also it has much more quests that have an actual plot (in ToA your quest usually looks like “help Trudy get wrecked for magic or something Idk, just find him some cock”). I think the difference with ToA is there's a tonn of characters, and making some complicated quest lines that don't work the way of “go there, there, and there, congrats” with all of them around is more difficult.
Overall, I think that for the current state of the game the best thing would be a new alternative to gallery and progress screen. Some notebook that is teasing you by showing what cool content you can see, hyping you up, eliminating the feeling you're on the fool's errand of going through the game again and again when you can fap to 25% of it and leave. There are various ways of doing them, but they all need some work done.
