Feel free to reject this run, because there are easily some things that might violate potential future rules.

• I used a launcher that sets custom DAS, ARR and softdrop speeds. Different launcher may have different possible values to set for these settings; and in most cases they are not values that can be set in vanilla Tetris Online Japan.
• I used a modded game, as you can see, or rather hear, from its different music and sound effects. While my particular mod only changed audio assets, it is still possible that someone might run on a modded game that has altered gameplay.
• I did not have an RTA timer, instead I used the in-game time to time my run. However, most other games use RTA to time their runs.
• Side note, while I did indeed connect to the Tetris Online Poland server, other private servers of this game also exist. I do not know if connecting to a different server can have an effect on single player modes' gameplay.
