To be honest I have much wrost expectations about the time needed for Ver 0.3 to be a thing.
NumericG. stated that
"(...)The characters for Ver. 0.3.0 are still being worked on, but I think it will be a while before they appear in the game. Modeling and design are in progress in parallel with Ver0.2.0, but we won't be able to start making Ver0.3.0 in earnest until after Ver0.2.0 is finished......."
and also
"(...)My goal is to have all the characters modeled and set up by the end of 2022. The characters are the most important part of UnderTheWitch, so that's what I'm focusing on right now."
IMO we will be very lucky if something ( maybe some stand-alone scenes) will be released for july or august 2022 and still then I don't think he will deliver more than 2 characters for the end of this year.
