Thank you! Glad you got a laugh out of the game, that is something I very much would want for people trying it out.
Looking down is a pretty frequently requested feature, I'm a bit resistant to it only because I don't want to add too many new buttons to the game (and Down is taking up by blocking) but I'll keep that in mind and see if I can find a happy middle-ground!
As far as release goes, pretty much every game always gets their release window wrong so take this with a grain of salt: given that Book 1 took roughly a year to make, I'm guessing each book going forward will take 1 year, and the plan is for 4 total books, so probably sometime in 2029?
