Luckily I can understand russian, but adding some subtitles later on would be nice for those who don't understand it.
Looking at the game itself, the aesthetics were nice, but it was missing something. There was no time limit, nothing in particular. Just trying to get a parcel and delivering it. I liked the game concept, but for me, it didn't really feel finished for me. Sadly I also didn't see the theme get implemented.
Putting that aside, the game felt aesthetically very pleasing. Maybe you could add a timer which would indicate how fast you should deliver the parcel. Maybe that would spice up some things.
