“Sucubus Heaven” is a roguelike 3D action game that challenges players to explore dungeons filled with miasma and curses. You lead a party of three characters, progressing through dungeon rooms one by one, managing your resources carefully to reach the deepest floor. Players control one of three characters, each with distinct traits, engaging in real-time combat. The action system is simple, with basic “Normal Attacks,” high-damage but resource-consuming “Special Attacks,” and “Dodging” to evade enemy attacks. Successfully timing a dodge results in a “Perfect Dodge” that can be followed up with a powerful “Perfect Dodge Counter.” All enemies attack the heroines to sexually assault them. Physical attacks wear down their “Magic Clothes,” while sexual attacks increase their arousal. When the arousal reaches its limit, it accumulates as “Corruption” on their bodies. The more “Corruption” builds up, the weaker the heroines become, eventually losing the ability to resist. These events occur in real-time during battles, so even characters not being directly controlled are constantly at risk. Additionally, the dungeon is filled with lewd “Miasma,” and the longer the battle lasts, the more the characters are affected by it. It is wise to finish fights quickly. Upon completing a playthrough, players receive a score based on their performance. Depending on the accumulated score, new “Loadouts” and “Boons (Blessings/Curses)” are unlocked. If the game feels too difficult, you can make it easier, or if too easy, add more challenging conditions.
