Thank you! Calendar year, in the evenings and on weekends, with sprints of several weeks and a month or two of rest/AFK after each sprint to keep sanity (I have a full-time job, a wife and a 3 year old kid). Happy that I had the persistence to keep working on the project

Very impressive! Thanks for sharing, it's encouraging to me and I hope to others to know that with proper time management we can put out amazing work.
