this seems to be a cheap groundhog day simulator. you can have the same conversations every day, nothing progresses, everything outside the house and some parts in the house are "in progress".
after trying the same thing for several days you may get some progress, but it's slow and tedious. clicking around and seeing if a new option pops up somewhere.
language is partly russian, partly very bad english.
oh and the download could be around 200 MB instead of 800 MB. it contains 4 versions which are 99.9% identical, just different ren py libaries. there is no reason to split it up like that.
