I just posted a video about my game, Tritris, it's Tetris with Triangles! You can watch it here There are even some highlights from when Jonas Neubauer played!
Excellent revisit of this variation, it is really tough! hopefully, your video reveal some of the strategy to perform in the game as at first sight, it seems complex to create a lot of lines on it. also you didn't put the link to the game so for the one who are interested it's here : Play Tritris at https://goel25.github.io/tritris
