How to obtain a star from Montris 2

I made a video of obtaining a legitimate Novel Games star from Montris 2.

Although that game isn't listed in https://www.novelgames.com/en/single-player-games (currently 547 games), it is possible to obtain stars from it as I show in the video. This star is therefore a star outside the 2735 stars, but is still legitimate.

Since Montris 2/3/4/5/5 Death/ZS are 6 different games, and it's possible to get up to 5 stars in each of those games, this allows for up to 30 stars if you play professionally enough.
