[後半に日本語レビューあり] [h1]Overconfidence Will Be Your Undoing: A Power-Unsealing H-SRPG[/h1] This is a turn-based H-SRPG in which the demon realm's supposedly strongest soldier infiltrates a prison built to hold succubi, hunting down a legendary shapeshifting incubus who has gone into hiding there. The premise is built around a heroine who normally keeps the vast majority of her power sealed away, gradually revealing her true strength as battles progress. The main appeal lies in the push-and-pull of releasing that sealed power. Spending action points to unseal it sends her stats climbing, but push the release too far and a gap opens up, making her more vulnerable to enemy H-attacks. Taking one permanently drains her magic power, and every subsequent battle grows more disadvantageous in a snowballing way. The more her confidence grows, the further she falls under this design, creating a tension that goes beyond a mere display of strength, and personally, this push-and-pull alone was enough to make the game genuinely "worth playing" to me. Getting bound triggers a mash-to-escape QTE, and the weaker she becomes, the more input the escape demands, with repeated failures forcing a hard cut t…17 found this helpful
Points for originality: The developer tried making a turn-based strategy game on RPGMaker. The result is that the UI and the gameplay systems are a confused mess; the gameplay is bad, and the core gameplay systems are obtuse and convoluted.4 found this helpful
Developed by RiceReng and published by Saikey Studios, B-Prison Unchain is a fantasy turn-based RPG that mixes strategic combat, character progression, and an anime-inspired narrative within a mature setting. Although its adult content is a defining aspect of the experience, the game also places considerable emphasis on storytelling and tactical gameplay. Players take control of Misa, an elite warrior serving Demon King Gilad, who is tasked with entering the notorious Chastity Rock prison after the legendary incubus Asmodeus escapes confinement. Asmodeus possesses the dangerous ability to disguise himself and absorb the strength of other demons, making him a growing threat that must be stopped before he gains enough power to plunge the Demon Realm into chaos. The game's story unfolds through a combination of exploration and combat as Misa ventures deeper into the prison's dangerous corridors. Along the way, she encounters imprisoned allies who can be rescued and recruited, giving the adventure a stronger sense of progression and reinforcing the idea that she is gradually building support against an increasingly powerful enemy. The prison itself is filled with hostile creatures, hi…1 found this helpful
Short but really quite good. It's fun, Misa is cute, the loss scenes are great~
Very good turn based combat, interesting mechanics, very original, a hidden gem. H content is baked into the turn based combat very well. There is probably a great review out here with all the tags. Don't forget to get the patch.
Misa is cute as a button! I love that bratty voice they gave to Misa, it suits her perfectly. Fight through the stages and progress the story, very straightforward. You win, story progresses. You lose, you still win by seeing Misa in various situations. You will never expect the twist at the ending. There is a bonus item to be obtained at the end for the second playthrough, look forward to it.
