I discovered OSU through a twitch streamer who I watched play other games quite a while ago. I tried a couple of songs and saw how god awful I was so I quit. About a month later, my interest was sparked again randomly due to my boredom, so I went on youtube and looked up OSU. The first link was of somebody who was playing OSU Mania. It was completely unlike the OSU that I originally was introduced to, so I decided to give it a shot. It was very familar by nature since I used to play a bit of guitar hero and some standard flash rhythm games. I am now pretty damn good at OSU Mania (although far from perfect). I can play any normal song and about half of the hard ones and score an A or S on them. Due to the amount of lobbies available in OSU vs OSU Mania, I realized that it's pretty necessary for me to get good at OSU to have fun and be more integrated in the community. Are there any tips that you recommend? Should I assign my keys different from the standard Z and X? What exactly does the C key do in OSU...? Is a pad absolutely necessary? Why do they use 2 keys as opposed to just one? Why is it so much easier to fail a song on OSU as opposed to OSU Mania? I will be grateful for any tips. Thanks!
