Yeah, I'm working out a full translation of the game. It's going to take a bit since as of this post I maybe have about a third of the game translated. That said I've been in contact with mikotoshi-dou regarding making some mod content for the game as well. Since I got his permission, that means once completed I can only release the modded files. You would simply have to overwrite the original game with the modded files and it should work. (Be sure to make a copy of the original game first however). Anyways here is a list of some changes made in the mod. There is no release date but I'll be sure to let you all know once its complete.
-New over-world map travel system.
-Added more fairies to the main base with some unique dialogue depending on your belly, bust or both sizes.
-Increased the amount of parasites produced from fertilization. Now it should feel like a more pressing matter that if fertilization occurs your belly will start to grow.
-Changed the worm area in game to mostly include worms that attack breasts, there is one worm that will attack urethra but you have to go out of your way to find it should you wish.
-Added a new herb to the west forest where all the worms live called milk weed. Harvesting it without gathering gloves will result in you getting poked by milk weed needles, increasing your bust size with milk.
-Added new craft-able healing potion that restores 45% HP and grants 1% Breast Experience. Costs: 2 Milkweed, 1 Breast Milk to produce. Requires level 1 medical station in house.
-Added several new buildings to the main village as lilia's house is upgraded, including several houses, a tavern, a barn, and an armory.
-Added traps to dungeons --Swamp dungeon now has mushroom estrus traps --Erosion forest has tentacle ejaculation traps
-Swamp dungeon now has a new collectible herb called "Fertile Mushroom". Without having the gatherer's gloves item in your inventory, attempting to gather this herb will cause Lilia to gain the Ovulation state resulting in an increased chance of fertilization occurring.
-Added tentacle monsters to the swamp dungeon, also expanded the 2nd floor of the swamp dungeon.
-Added Witches house to the swamp, she will trade EP for fertile mushrooms. Giving her mushrooms will cause her to... eventually become pregnant.
-Added new sprites for Lilia for her normal clothes, if have a large enough bust it will be reflected in her sprite. If you have a large enough belly it will now be reflected in her sprite. Should you have a large bust and belly, it will be reflected in her sprite.
-Should you become too large in the bust area, lilia's speed will be reduced.
-Should you become too large in the belly area, lilia's speed will be reduced.
-Should you become too large in the bust and belly, lillia's speed will be severely reduced.
-Fairies located at the lake and at the west and south coast will now sell goods related to those areas for an increased cost.
-Added a statue to Lilia's house that will eventually allow you to buy unique passive perks based upon sexual experience. In order to unlock said perks, you must reach a certain level of sexual experience per body part
---More to be added in time.
