Changelog

v1.0.1: Major: New Dead Rail Event - Visit the Imps at their home, and finally get a H-Scene for them. Players that have cleared Dead Rail may need to use the 'Replay' function. Added a 'secret' epilogue scene after beating the main story, beating Pyraxis in the simulation, then going to sleep (People were a little sad that Pyraxis didn't seem to get a resolution, so here we go!) Minor: New Cheat: 'One Punch Man' - defeat all enemies in one hit! Mosquito Girl's First Encounter: Her HP and ATK now scales from 50-60, and 6-8 depending on the day you encounter her. (This was done to help prevent an auto-loss if encountering her on Day 2/3) Added some extra dialogue to the first bed talk. (I was just experimenting with what deeper dialogue options might look like for fun and decided to slip it in.) Fixed Daily Mag not fully increasing with Wit, and nerfed the Mag Gain by 50%. (Now 100 Wits = +50% Daily Mag. This should balance out the Esper tree being 50% more expensive than the others.) Kitsune Support: Now actually works (sorry) - implemented a scaling cap equal to 12 + Monster Rep Small Mortivira nerf: All sources of damage in this fight deal 1 less damage. Black Candle no longer deals extra damage in phase 2. (Mortivira ended up being the hardest battle and a little RNG dependent, because not only did you have to deal with strong minions, but her spells were just as scary as any of the other superbosses. Hopefully this adjustment will give players more breathing room) Misc: Fixed some scenes not resetting Protagonist or Tatsumaki's lust Fixed Explosive Vial A causing Poison and Bleed to proc twice Fixed 'Discern' not working in the Azazel fight, causing her clones to pop instantly Fixed individual doppelganger scenes requiring x2 potions Fixed Cauldron 3's Tooltip from +1 Wits to +2 Wits. Fixed Acid Flask A and B not granting an additional Flask. Fixed HP Regen from Cauldron7a not getting subtracted when selling. In fact, it was actually getting added again when selling! Fixed a crash when looking at Data Khaos' second tip. Many many Typo fixes v1.0.0 Major: +1 Advanced Act: Full Nelson +1 Outfit Scene: Wedding Dress +2 Transformation Scenes: Werewolf, Preganncy Added Zone X: Super Boss Zone with 6 Super Bosses and 6 H-Scenes for successful victories. Story: 5 New Events, including the finale. ~16,000 Words of New Content Minor: 6 New Encyclopedia Pages Wits now increases Daily Mag. 1 Wits = 1%. The hidden defense stat has been removed and the game has been rebalanced around it. Most enemies have a lower ATK value. Physical Skill HP Costs have been reduced Blood Lash A: Reworked effect. Bonus damage is now dealt as a bleed DoT Final Toll: Costs 50% Max HP -> 50% Current HP. It can now always be used. Final Toll A: Immediately refund half the HP spent -> refund all the hp spent Healing Potion B: No longer heals additional HP. Now gives +10 Max HP. Acid Flask B: New Effect, 'Debuff Potion,' inflicts +10% Stun, Poison and Evasion. Toxic Crescendo: Base damage increased. Now tells you how much damage it'll deal instead of a %. Is now a guranteed critical hit. Toxic Crescendo B: Buffed to give 2 of all the debuff potions, and 1 additional Toxic Crescendo Wind Blast A: New Effect: Causes enemies to take bonus follow-up damage from your attacks. Wind Blast B: No longer deals bonus damage, or costs more MP. Barrier A: Now deals damage equal to the amount of barrier gained x 2. Passion Unleashed A: Now Costs 10->6 HP on Cast Silent Eclipse B: New Effect: Every Turn: Gain shield equal to 10% of your Current MP while Silent Eclipse is active. v0.5.0 Major: Advanced Acts: Anal Cowgirl Transformations: Giantess, Fairy, FFM, FMM New Area: City Ruins, +2 Monster Girls, +5 HCG. Story: Three Events, +1 Sex Scene Minor: New character model for 'Genos' New Clothing System: Added Goth, Gyaru, and a Winter dress for Tatsumaki. Added Gyaru styles and Casual dress for Fubuki. New Supports system: select up to three supports to appear in battle. Support powers now scale with your reputation. Inventory and Passives menu improvements. When an area reaches 100% completion, you can now select an event from that area to replay. v0.4.0 Major: Advanced Acts: BGSM, Public, Zero Gravity Transformations: Cow Girl, Horse Girl Outfits: Maid Story: Three Events + 1 Sex Scene. New Area: Block 7, +4 Monster Girls, +4 HCG Minor: When selling a skill, its upgrades are now automatically sold too. Added a cheat to rename characters at any time (including the protagonist) Follow-Up Attacks (such as Marked for Death) now appear as damage numbers instead of text boxes. Added damage numbers for enemy attacks, player healing, shields, and even MP and Lust gains/losses. Since the game has an ever increasing amount of passives and items, this'll help them keep track of everything. Defense now scales with all stats, but is twice as effective with might. Mind Flare now lowers lust by 8% Misc: Fixed some items and upgrades not appearing in your inventory/passives (the rings won't appear on existing saves) Fixed Esper abilities not being usable without having purchased Wind Blast Update Passion Unleashed damage formula (overall nerf). Fixed Passion Unleashed A's bonus damage. Fixed a bug where if upgrades that gave HP regen were sold, you kept the HP regen Updated parts of Vital Gambit and Unyielding Force descriptions from 'Cleave' to 'Follow-Up Attack' Mag on the UI now always rounds down, preventing rare instances of not being able to afford upgrades even though it appears you have enough Mag. Fixed an issue with the Cultist fight if you have Last Stand and accept their invitation. Fixed the player not gaining cunning during the Tunnel Siren event v0.3.0 Major: New Advanced Acts: Anal, Reverse Cowgirl New Transformations: Dog Girl, Oni New Outfits: Goth, Gyaru New Area: Dead Rail, featuring: 8 Events, 4 Monster Girls, 3 Lewd CG New Story Event: 5 Monster Girls Cauldron Update: Massive Update.

Added a combat simulator, allowing you to replay battles. Damage numbers appear differently depending on whether it's DoT, a Crit, or a regular attack. Wits gives more mag on affection increases Tons of small changes; I checked through the entire game from the beginning Misc: Fixed an issue that caused save files to bloat. Expect all of your save files to spontaneously decrease in size by x10. Added a loss and flee condition to the Chimera vs. Imps battle Fixed an issue where camera position wouldn't be reset if sex camera movement was turned on 'Acid' status from Acid Flask now correctly resets between battles.

GO! GO! ZEPPELI 2026-04-10 ★★★★★
Unironically enjoyed the combat the most, decent scenes and lotsa dialogue. Spent some time maxing out all the skills and exploring everything there was to offer. I liked the original characters a ton and the romance with Tatsumaki was well…

Plot: I think it's excellent and lovey-dovey. It's very positive and brings energy into my life. Graphics: I think it's pretty good, judge for yourself. Gameplay: The combat system is very interesting and has various combat styles to choose from…

This is probably the first time i've played a game from this website and didn't feel like a complete degenerate afterwards. Definitely not my style, but sometimes its good to fap on something where nobody dies or suffers permanent physical…
