My personal life is quite busy, but I work on this project whenever I can. After a release, I start working on the next version on the next day or two just to make sure that I respect my commitment to a new release every 4-6 weeks. Since the initial release, I have respected the 4 weeks' schedule so far, but next month, I will be on a 2-week trip so the 0.05 release may take up to 6 weeks for that reason. I'm completely transparent with my game development; I'll make a post to let you know if there is any delay whenever it happens.
When I feel confident to release a new version every 4-6 weeks consistently, I will open a Patreon page (maybe not before 0.1 beta release), but I will still offer a public version of my game just one version behind. The reason I didn't open a Patreon page just yet is because I would feel uncomfortable to charge for content that I cannot guarantee to deliver on time, so until then, the game will remain free.
