I'm using one that allows me to make the programming as enjoyable as possible, since I do everything myself: Narrative, Characters, Environments, Programming... But honestly, it's a lot of work and the fact that the game has been uploaded so fast on pirate sites, has completely broken my patreon flow. It doesn't really motivate me to continue developing the game.
i've see many developers before taking this either or good manner or bad manner, both are respectfully understandable, but hey, pirate games is almost from people that dont will pay you anyways and people that want to see if your product is good before buy it. for my side, im willing to pay for the end product and dlc's if you make it, its the most promising story of a one piece h-game ever. the other good side of this is that you can take all the feedback to improve and attract more patreons, your game is amazing, just dont feel bad for piracy, every game have his thread in this forum, its a sign of good work. i put you the example of aurelia from mirthal, the developer is active here and help the community in his time, after the game came out in steam a lot of people went from here to buy it. use us as advertising, more people will know about you from here, more people will be interested and eventually not all but the people that truly loved your work will buy your game. its a win/win, if you feel overwhelmed by piracy you would'nt see the entire picture. take the thread, keep the good work, if that engine is the only you know for work. okay, just some considers: gallery doesnt work, some dialogues bug and you need to load a previous save, the scenes are to slow, animation is good but i recomend to put more angles. story is promising as fuck. game crash outta nowhere sometimes. make more fluid the transitions and keep fixing bugs. when a first truly stable version of the game is out more people will be willing to give you money. good luck master <3
