Make the game free to play. I don’t know if you can influence the pricing policy of the future game, because you are developers, not publishers, but nevertheless I would like to ask whether you considered the free to play model as the main one and why did you abandon it?
More and more often I come across games, that upon release became paid and not only scared away the audience, that was gathered during demo testing, but also failed to gather a new audience, because promoting the project required funds that some companies/indie companies did not have.
I say this not from the point of view of attracting an audience, but from the point of view of profit.
Free-to-play model can bring more income than other models nowadays. For example Warframe/POE.
In any case, I hope you don’t abandon the project and the game becomes popular.
