Much as I completely loathe the Tetris Company's "guidelines" (read: mandates) around controls and rotation, I've been compelled by the 40-line mode in Tetr.io. I thought I was only really decent enough to get a time of around 1:30 - 2:00, but I've somehow kept pushing it further and further down, and I'm gunning for a sub-60s clear.
Although, even if I don't ever get there, I'm quite chuffed with my current PB as-is: https://tetr.io/#R:eKipgonCOw
Graaaaawr, I did it!
