Sorry, peppy, for let you reading my emotional thread out there.
Please let me explain some misunderstanding.
The MAIN reason i think i'd better to leave is: I can't understand you. Not all the reasons i list in thread.
In details, I'm working in a Chinese game company which provide games for nearly 300million players, if some cases like hitsounds (Opposed by lots players) happened in my company, we will remove it and release new build the next day.
It's nothing about whether i like it or not, but players like. Serve the players, is what i learnt in past 3 years in company.
Although osu! is not a commercial game, but I believed in the creed.
the second MAIN reason is i feel guilty for mania code, it's really hard to understand (even me at now) and i want to start from zero with a new mania, which i think it's impossible to implement that project based on osu. If i really start the project, it could be a opponent of osu!, so it's better for me to choose quit rather than work on both.
About the github operation, i just deleted some really old branches which won't be merged.
