I'm gonna be a bit honest, giving people unlimited actions isn't going to make them join your experimental forum game, being a good host is. I'd like you to understand the concept of good faith. People are more willing to try experimental games if the core idea is sound and the host has a good reputation, and has shown that they can handle their own commitments and host good games on their own, so they can join in good faith that their time won't be wasted. As it stands, people aren't going to give you the benefit of the doubt right now since this is being run straight after the already subversive Midnight Hotel―a game which required similar levels of host input that flopped because of a few reasons, but the primary one being lack of host communication and consistency, which seems to already be causing the same problems right now.
Following that game, admitting you've only put a few hours of thought into this game, and claiming its something which you intend to run endlessly, doesn't inspire confidence the game will be sustainable for you or its potential players at all. As WT succinctly put it, there's nothing to stop everyone from thinking you'll just get bored of the project and move on, and nothing inspires faith that you will commit to the idea fully in the first place.
What about D&D? That's kind of an"endless game with a GM".
GAH! I'M SO BAD AT THIS KIND OF STUFF AND I WANT TO DO IT SO BAD KAVFMBKRVMLLVMLVM
ignore my little temper tantrum lmao
D&D is not normally endless. There is usually an endgame planned from the start, and many quests and goals to reach in the meantime. A game lasting for 38 years is a massive outlier, and even then, the campaign likely still has proper goals that can be reached, but likely exists as "endless" because the world setting never changes and new villains show up.
Slight tangent: good faith does not involve acting entitled. Even if you want to do it so bad, complaining that no one is joining your game while insulting the one who is actually trying your game isn't right and will actually drive away people who might be interested.
Lastly, good faith aside, people might just not be interested in the core ideas. Midnight Hotel was occasionally fun and with a bit of advice, I definitely think you have the potential to host something great in the future, but I would take the feedback others have provided, develop your ideas a little more, and maybe try hosting some other games that actually have goals and can be completed (and complete them) to perhaps garner a better reputation. At the end of the day, we only have so much free time on our hands, and can only commit to a certain number of forum games at once. If people don't think it's worth their time, they won't join, so there needs to be confidence that the host will make it worth their time before sign-ups occur.
