pretty much everything Jango Mango said, it really depends what you want to do in the future, quality over quantity is nice, but if you like the approach of making quick games for stuff like gamejams, its fine! for me personally
i do fall in the same rut of working on a project too long that i eventually get more interesting ideas to work, so none of my projects actually get published. if it was up to me, i would do what i want while seeking others advice aswell, you wouldnt want to suffer making something that youre not happy about haha
still, if what gets you going is small bite-sized games, but you want to try making a bigger, more developed project, then go for it! my input may not be that good, but i hope it gives you some insight on what to do!
