There is an abundance of gear in the game and yet very little use is made of it.

Enemies should have random chance to have toy fetishes and therefore will attempt to use toys in combat.

Enemies should attempt to put the player in chastity.

Loot should be a possibility in combat. Some of this loot should be unidentified. This unidentified loot should carry the risk of debilitating curses, lower stats, or mind-altering effects that force the player into certain actions.

Some gear should be feminizing or masculinizing.

+1 for transformation, forced chastity, and maybe loot

I'd like different clothes tbh. It doesn't even have to require the class change. 

I.e. Just have Hiro appear with the mare, school, beast master outfits etc.

I still feel this way about underutilisation of gear to drive interesting and varied gameplay runs.

The principle mechanic of almost all roguelikes that makes them interesting and replayable over and over and over again is the fact that variety occurs from run to run. In all roguelikes this variety is derived from items and gear.

Tales of Androgyny has great ideas, great art, great combat, and great writing. But it lacks variety from run to run. Encounter outcomes with different monsters are always the same, the player wins the fight and/or the player loses the fight and gets the one single negative outcome that a given monster has to give to the player.

This can be fixed, drastically changing the gameplay and replayability of the entire game, simply by adding gear to the game with varied statuses. 

Cursed gear. 

The need to "identify" gear at a cost or take the risk it might have negative outcomes by wearing it to test it. 

Gear that lowers stats.

Gear that feminises.

Gear with mind control.

Gear with real gameplay affecting RNG.

Etc etc.

Gear should be delivered to the player inventory via fight wins where the player can decide what to do with it.
And the possibility of forced gear being placed on the player should occur on losses.

This will provide interesting outcomes, for example the player might acquire a cursed tail plug which would force the player into making new decisions about werewolf encounters until they can remove the curse. It changes the conditions that the player is playing under.

This is completely balanceable by making the average value of gear that you acquire to sell equal to the average cost of curse removal in an average run where a player takes risks. This approach to balancing it would not affect the existing balance of hunger as a mechanic intended to force the player to progress. 

Having everything delivered to the player via predictable encounters makes the gameplay extremely samey once you have already experienced those encounters. It is the variety of potential outcomes and runs that makes other roguelikes replayable over and over and over again. When I meet a werewolf every victory or loss is always the same, this stagnates gameplay in the longterm. With the impact of random loot to the game every victory and every loss can become gameplay altering in its own right, creating a real sandbox.

I like the idea of variety coming from items, as for right now I basically know what I'm going to use in every run — Rapier, Reinforced Shield, Stats Gear, Full Plate. Most of toys don't have any use besides being removed in battle. So it would really be cool if some common enemies (common because they're making crowd basically, it won't ruin impression already built for more unique characters) would somehow interact with you using your toys or even theirs. The example we kinda have is the change in behavior of Male Goblin, who will give you a different scene when you're plugged. Imaging Brigand giving you beads run when she's aroused.

And outfits are really having potential to only only be cosmetics, but at least raising Lust more or giving additional Charisma. For example for certain types of enemies, like some will prefer cat suit, and some are really into mare one.

WIth that I'm thinking about additional stance for making love, something like deep casting, only deep romance. Giving you options in more complex foreplaying, that can also involve toys, maybe even having own mechanic of delayed arousal to not be ended so soon. It's just I can't stop feeling all those skills in sex are mostly not worth investing in, because they're changing only the letters in log. And most of love you make ends pretty fast, so it's time to rework this in-battle making out system.
