Tried out this game for a few minutes. It's looking really promising! I like the art style and the girl model is great! I could critique the combat or gameplay but since it's early I'll let the gameplay aspects get fleshed out later. Now onto some suggestions (mostly what I would want to see):
Very quickly, the most important thing I'd suggest: Integrate lewd with gameplay / strategic decisions. Lose to see boobs is bad. I want to have seeing lewd things done progress the game and not have it be a game over defeat screen like oh so many RPGs. I love those RPGs but saving before each boss fight to intentially lose and see the scene and then reload to win the fight is not engaging gameplay.
On the topic of getting "fleshed out", that would be something I'd like to see! Leaning into the roguelite aspects with developing the girl's assets each run would be great. It ties in the progression with lewd elements. You could also make it so developing certain assets improves the girl's combat capabilities. Bigger boobs -> fire attacks, bigger hips -> defense or offensive-defensive moves ala spikes, sensitivity/pussy(shown as a lust crest?) -> summoning skills. Another roguelite that does this, it has vampire survivors combat instead of turn based but don't mind that, is Wedding Witch where you drink potions to make your boobs bigger/smaller or your muscles bigger and developing different assets unlocks new skills. Basically you decide to go for making your girl's boobs bigger since that effects your build. Lewd with gameplay!
It would also be cool to potentially see further development on this tension system. Using lewd attacks on the enemy for advantages in combat! We could tie this into developing the girl's assets by making things more effective like tease if she has wider hips etc. Last Evil has this combat sex mechanic alright. The player character is a succubus and can have sex with an enemy to temporarily take them out of combat. It could have been done better but it's alright.
Clothing. Cool that we can buy skins with gold. Would be cooler if it was part of the roguelite! Consider artifacts being clothing items or having equipment be another seperate thing. Seeing our character develop over the course of the run is one of the best parts of roguelites and while traditional roguelites see this through the evolution of your character's build, lewd roguelites can easily add lewd elements by having your character dress up in skimpy clothes because they boost fire dmg!
Anyways, feel free to ignore all of my ramblings. I'm excited to see where you take this game, and try not scope creep your way into abadoning the game, keep at it!
