Take as much time as you need. There is very little need to rush unless you have a deadline and most solo devs do not have that kind of date limit. Yes there may feel like one with promises to a community but like silksong and deltarune has shown people can wait for results or a working game. There may be a few that want it rushed or complain but can never make everyone happy. Play towards your target audience and make something you are happy with creating.
