The only positive thing we can say is that the bot appears to be - at best - slightly above average with Tetris 99 compared to an average human. Which makes it pathetic at this task considering it is a bot and should have near perfection with minimal effort. One extra slightly above human has little impact in the game honestly.
They don't do T-spins. They don't stack large attacks for KO's, or even seems to alter targets under any condition at all even. The targeting reticule is hard stuck on attackers with zero input put into it. So it has no overarching strategy besides survival, but even then, it doesn't try to play the badge stealth game either - backstabbing a leading player is the leading method of making comebacks, and necessary ones too. Which is why it reliably gets in the top 15 and then loses, you can not outfire someone without badges, there ARE one-shots in Tetris 99, the bot probably only won when it lucked out early on in being the leader of the pack and then fed on a crowd of people with targetting set to "badges" (there's a firepower multiplier when targeted by many people).
Which is... kinda pathetic reading into when I'm someone who reliably got top 3 outside of the Invictus mode. I think the creator might have 0 idea of what defines Tetris 99 at all. Like, straight up no awareness whatsoever. They're bad at this game, and thus, made a bot equally bad and only wins with luck.
It's just playing normal Tetris. It literally has no reason to do this against humans, does nothing with the human element. So it'll beat other clueless humans and then lose to the actually good humans. Between those two human groups, they're just one more in a sea of typical indistinguishable threats and fodder.
Good on the creator for stopping before making something more competent.
