I got to the end 2, for me it was also missing the milk and I think I'll leave without paying lol
PS: I saw that your project has a problem with V-Sync "those lines that cross the screen" do the following, in the game folder, in config, find the file "DefaultEngine.ini" open it with notepad, find the "rendering" section and include the following code at the end: r.Vsync=1
Otherwise I found it fun, despite being very short
