I want you to know that you have value to me even when you aren't actively working on the fangame. I know what it's like to need to take time away from stuff to just... exist. For me it's fan fiction rather than fan games, but I still need time where I need to just put that stuff aside for a while. Just because you enjoy working on a thing doesn't mean it isn't a mental burden. And sometimes life just doesn't leave you the time/energy you need for passion projects, this time of year especially.
So yeah, take your time. No pressure. Seriously, Rejuvenation is already locked in as my favorite Pokemon fan game ever regardless of how things go from here so I'm happy to wait however long.
