You see the "out of memory" line in the error you caught?
Sigh.
Apparently, if you don't have like (insert tons of gigs of ram here) Her Heart's Desire won't work. I learned from this project there's a reason I have more animation in a single edition than _any_ other Ren'py game, bar none, in full HD.
It just won't work on smaller, less equipped machines.
Don't be like Brosef Chungus, and deliver the biggest, because not everybody can handle something *too big* you know?
Also I noticed a few deveopers here lately who don't compress their images at all, and even with less than half the static content in my game (and infinitely less animation) their games end up over 5 gigs for a download. This is less than 2, which I think confuses people who don't realize just how massive it is, when it's a Mr Chungus experience
