I don't know if it's worth anything, but I'll offer a list of the improvements I noted could be made while playing this. I am keenly aware the every "improvement" I suggest means more work for you, but I genuinely believe that you have a gem here, and if you just work at it, you can produce a masterpiece. That said, these are just suggestions, the final say is with you:
1). Differentiating targets: during dungeon fights, there are times I encountered groups with two similar mobs, like 2 dogs and so on. Above the fights, there are icons showing in what order your fighters and the mobs will attack. To survive tough fights, I did my best to stun the next attacker to give myself some breathing room. But then, if the enemies are similar, there is no way of identifying which particular enemy is next, you just have to gamble and guess which of the 2 or more, similar mobs the icon represents. If there was a way to distinguish which icon represents which mob, it would make the fights much smoother and easier to strategize around.
2) Harder fights should give greater rewards: I get so frustrated whenever I meet other heroes in dungeons because despite the fact that they hit so much harder than normal mobs, there was no actual benefit to defeating them. I'd get the same trash loot as I would beating much weaker mobs.
3). Leveling up and stat distribution: Part of what makes RPG games so much fun, is the ability to shape a characters path in a meaningful way. More strength means more damage, more speed means higher chance of evasion, more intelligence means more mana to play with and so on. Instead of just saying that a character has leveled up and leaving it at that, give them a number of stat points (5 feels like a good number), and allow the player to distribute them. That way, a player is more invested in their character's development. Also, make the stats meaningful in the game, make higher strength mean harder hits, higher agility means more chance to evade. One point of MP can translate to 10 mana, (or some other multiplier, you decide). And so on.
4). Higher rarity loot should be worth more: How the hell does legendary armor sell for the same amount as uncommon armor?
5). Allow for the sale of Relics: I think that's self explanatory.
That's it for the strict gameplay suggestions, these are my content suggestions.
1). Animate the sex: While I personally don't mind still images, I've found that I really enjoy games with animated sex scenes, so I think that will elevate your game as well.
2). Random good/bad events both outside and inside the dungeons: After playing the game for a while it can feel a bit repetitive. To spice it up, you can add little random events here and there to keep the player on their feet. They can be both sexual and nonsexual. They can even turn out good or bad based on the player's choices or whether certain stats meet certain thresholds. They can offer rewards like, gain in certain stats, gain coins/ armor/weapons/relics, or even a sexual encounter. The punishments naturally will be the inverse, losing stats/money/armor/weapons or missing out on a sex scene.
3). Sexual mechanics in combat: being able to strip your opponent mid-fight and perhaps taking things further, should really spice up the fights and make them that much more enjoyable. Perhaps you could put in a seduction mechanic for the female fighters, making any male enemy mobs commit a sexual act after which they either lose some health or become docile/fatigued for a turn or two (just spitballing here). This can go both ways, if a character's resistance isn't high enough, they can be seduced by enemy mobs and suffer the same ill effects for a turn or two.
4). Put in a corruption mechanic: Allow characters to start out good but increasingly become more depraved as time goes by. This'll keep players hooked as they always wanna see what's next. If they have access to everything right from the start, then there isn't much to hang around for.
There are so many haters on here that have never produced anything themselves. Ignore them. If you allow them to get to you, it'll be a real shame. I said it before and I'll say it again, this game is a gem and I truly believe you can make it a massive hit if you just stick with it.
Good luck.
