Probably the most well made and advanced introduction cinematic, by far I would say.
I do not speak Russian, so I have little idea about what is going on. The English-language subtitles are nice, but a lot of voice audio is only in Russian.
My system may be too low-end, but a lot of the time, the game was too dark for me to see the ground, meaning I ended up falling.
I did succeed in clearing at least one stage. I managed to get to the part where there is giant nightmare Bokubes.
The game has multiple cinematics, which is rather nice for a game.
The game is in many ways surprisingly good. A lot of the time, I had no idea what I was doing or what was going on (neither story-wise or gameplay-wise), but I did manage to get some distance. The gameplay can be rough, but still works. The author of the game is both talented and competent in programming and other fields.
