snatching a falling block and swapping it into a match does take perfect timing, though
personally, i think the game works best on easy at any speed. i mostly play endless these days because the cpu doesn't offer much challenge anymore.
that being said, jump on panel attack where everyone is playing hard with high speed, and it gets pretty insane. i find it a little too touchy, but can hold my own as long as i'm not aggressively advancing the stack to the top, which works on easy but is asking to die with the settings people usually play. there's a discord too for finding matchups and they run tourneys too, but i haven't jumped on in ages (i don't have a controller for my computer atm)
