Hey friend! Thank you so much for the kind post, the team really appreciates hearing positivity like this, and we love hearing your ideas too!
We don't have a formal roadmap, we're a small team and we try to react to the community's requests as much as possible, so whilst we do have an internal roadmap of things we'd like to do, it's designed to be flexible on purpose so we can pivot if needed!
That said, the team is working hard on future updates, and we plan to bring both new content alongside new quality-of-life changes. Of course, that includes looking at things like DLC and seasonal stuff too. We can't share any info outside of that right now, however, we will share more as soon as we can ^^
