Turns out, even with a programming background as mine, with an easy entry software like Twine, is quite an enormous task. It took me 1.5 years to do something that could finally be called game, and even after that, my game only have 4 locations (I'm adding a fifth on the next update). If you go the open-world/sandbox/free roam route, be prepared to program, HARD.
Take your time. If you want, make a new thread on the
Programming, development & art section of the forum to see if you get players that test your betas, and improve it over time until you have something that can be published. You can gain a following even before you publish your game here.
Many devs go directly and publish their 0.01 versions right away, and improve the game with the feedback after that. but I don't recommend it, I started with a dev thread here (and also I had a discord server with other gay devs as myself, where I published the betas. that was lucky) and published many versions of the game following their feedback, until I was confident enough to have the official release rolling, along with the patreon. You only have ONE chance to get a good impression on the players, don't rush it. If you publish a barely playable game, with a patreon right off the bat, it won't net you too many subs. Happens a lot with Twine and VNs on Ren'py.
