Well, there was a big fight between BTMC and xQc. It was a massive event (relatively speaking), so that’s why everything happened so quickly and immediately always. But I wouldn’t be surprised if some people used bots to help out, but I know that most were real people who just sat there and waited for another pixel.

In Osu! (Standard, so the circle clicking mode) you can, by default, use Z and X aswell, instead of the mouse buttons. Standard is a long learning process, and if you do decide to maybe play it again, my personal recommendation would be not to get stuck on PP (performance points), it could really ruin the fun of the game, when you play the same song and map for the 100th time in a row.
Mania, I haven’t really played so I can’t really help with that.
A tutorial song and map should’ve immediately downloaded after installing Lazer, but if it didn’t, I recommend downloading it, cause it does help with the basics of Osu! Standard.
Also settings has keybinds and you can change anything to anything pretty much. I would recommend clicking around it.
Sliders you are supposed to hold until the slider ends, so as soon as it ends, you can let go. Reverse sliders (so the ones that have arrows and go backwards) you hold the same way and keep holding when it hits the arrow and goes back to the beginning, then you can let go.
Starting off, it is a lot to focus on, but you do get more and more comfortable with it the more you play. It’s the first game where I’ve really seen that play more to get better, because theory doesn’t help much.
If you do keep on playing, then more power to you. Top players are insane, so I’d recommend looking at someone like mrekk or Ninerik on Youtube. If you don’t then at least you tried it.
