Sorry for the rather late reply, but given that Ren'Py now ships two distinct flavours (versions 7 and 8, that is) running on different versions of Python (2 and 3, respectively), simply running a game on the 'latest' version is now even more prone to error than before. Especially seeing how even some minor releases of Ren'Py 7 introduced incompatible changes. Several developers that started on 7.3.x were reluctant to switch to the 7.4-branch, delaying the switch until saves became incompatible (which, given that those titles are still in development, shouldn't be that big of a deal to anyone, really, but opinions on that heavily differ
*shrug*).
In this particular case, 'latest' works, as the actual SDK used to build the title is 8.0.2:
Does this also apply to the compressed version?
