Add touchscreen support

Wrong slider SV bug

If you play the map "The Guinea Pig Is In Your Mind" on the top difficulty, then the last slider of the map has a velocity which is way too low. It causes the map to go on for a full 40 seconds after the song ended. This slider isn't so slow on the normal osu!

無法使用 Chrome 遊玩

这样的预览界面
我想在sb服（一个osu私服）的前端里嵌入铺面预览。

在线预览

我尝试过使用iframe嵌入，有几个小问题：

• 失焦后note会全部miss
• 没有办法暂停
• Master音量默认有些大

希望可以做一个更轻便的铺面预览功能

Spinner not properly working

Spinner should show yellow when completed.

游戏无法进行

按太早不会miss

在一个note上从缩圈开始出现时连打，都不会出现因为按太早而出现的miss，这不osu，也不音游。

账号系统 Account system ?

ip/cookie=账号不是很舒服，重拨号一下就换了

skin support

i really like osu web (its also the only way i can play osu) but there is only one problem and its no skin support i cant play that much well with the lazer skin

some issue on macOS

1. Mac 上 f11并不能进入全屏 。
2. 在窗口大小改变的时候，cpu占用极高。
3. Safari 无法加载Hit Sounds
4. 某些beatmap难度列表过长

Consider using Websocket with localhost server for low latency input capture and audio rendering

After setting up the websocket server, I found that the typical delay from the browser to the server is 0.21ms. This should be enough for the game like osu! .
I wrote this Websocket server in C #. If you use other compiled languages, there should be room for improvement.

触控支持

只能用鼠标操作有些难受，也难以发挥出web版本的优势（跨平台），要是能在pad上游玩就好了

想要这个网站的hitsound

如题，真的很好听 ，但是我把源文件的复制进去有些不生效....

error connecting to osugame.online

Audio issue

It's as if I can hear one part of the music, but the other part, usually the actually singing, can barely be heard, it also messes with the hit sounds.

add search/sorting in collection

title. also would be great if there's a way to see all downloaded map at once such that navigating through maps is easier

Unable to load hitsounds on iOS devices 无法在苹果移动设备上载入hitsounds

I am an iOS device user and I ran into a problem that happens on all of my iOS devices. On Safari browser, when I open the site, the hitsounds loading status freezes on that "loading circle" but my iPad status bar suggests that no internet activity is in progress(no loading icon). Please fix this as this is really bad.

我是一个iOS设备用户，而近期我遇到了一个发生在我所有iOS设备上的问题。在系统自带的Safari浏览器里，当我打开网站时，hitsounds的加载状态一直卡在“转圈”，但是我的iPad的状态栏显示目前没有网络活动（没有转圈）。这问题很严重，请尽快修复。蟹蟹。

成绩结算FC判断bug

列表重复问题

点击开始下载任意map，当map下载失败后，在第二次点击下载时，会新增加一个相同的项在下载列表，失败的项会一直停留在原位

连接被重置

搜索别的谱没问题，就是搜FD会显示连接被重置，要等2分钟才能再进去

Won't load

The hitsounds, skin, and scripts will not load causing me to not be able to play whatsoever. Does it have to do with the domain change and everything?

谱包含多个音乐文件时播放了错误的音乐文件

Skip function doesn't work

系统 macOS 10.13.6 浏览器是 Google Chrome 84.0.4147.105（正式版本） （64 位）
随便试了几个谱面(前奏长度大于30秒)，后来改了快捷键还是不行
希望能增加跳过前奏的视觉提示~

need to alert in case beatmap unmatch

When trying to download a beatmap it shows that it's completely downloaded and the audio seems to be fine however, when trying to select the difficulties for beatmaps, it doesn't want to seem to load the map even though, it completely downloaded.

Chrome 装了扩展导致浏览器报错：audios[i].softstop is not a function

downloader.js:11
Uncaught TypeError: audios[i].softstop is not a function
at startpreview (downloader.js:11)
at startdownload (downloader.js:44)
at HTMLDivElement.box.onclick (addbeatmaplist.js:366)

扩展举例：有道词典Chrome划词插件
应该是扩展的 标签早于页面加载导致，把扩展关了就好了。
可能需要在调用 softstop 前加个非空判断？

一些歌搜索不了

比如搜索
Don't say "lazy" (Full ver.)
Hisaka Yokomapped by DJPop这首歌关键词Don't say "lazy"
包含了"lazy"搜索界面就会空白
同时如果有玩家游玩了这一首铺面并且结算出现在了首页，其他玩家点击这首歌想要游玩的时候会出现undefined

一首歌显示出问题

Depopulated Zone-VacuumTrack
这首歌在首页会这样显示

Depopulated Zone-VacuumTrack [undefined] | undefinedx | NaN | undefined |   | NaN:

游戏中alert弹窗问题

当同时下载两张地图，地图1完成后并进入游戏内，游戏游玩过程中，地图2下载失败，这时候游戏内会弹出下载失败的alert框，影响正在游玩的地图1

Crash on SID : 493133

uncaught exception: out of memory

手机端帧率低

Android 8.1.0; vivo X20 Chrome/73.0.3683.0 Mobile Edge/44.11.2.4122
分辨率无论是降到最低还是拉到最高，帧率是差不多的，所以感觉不是分辨率问题

闪烁的 follow circle

Audio offset 设置疑似不起作用

调 offset 的过程中发现怎么调都感觉不到差别，试着分别调到 +80 和 -80 并只注意听歌不在意判定圈各打了一把，确实没有差别

是因为这项功能仍在 TODO 吗

Game wont download the songs

Everytime i try to download a song it just freezes the download or it wont download at all. not eve the pictures on the beatmaps will show up. it worked yesterday but now today it stopped working for me.

Map won't load

It does everything right until I click on the difficulty I want to play.
No matter which one I press it doesn't work.
It could be because I'm on a school pc.

audio of sid=28565 doesn't load

Change project name to avoid confusion / trademark issues

Really cool project!

Unfortunately, you've named it the same as the official game. Highly appreciated if this could be changed. You are free to mention that it is a game that "plays like osu!" or "based on osu!" something like this, but if it isn't changed by trademark law I will be required to file a formal complaint.

I'd also advise changing the domain name.

You seem to have included the copyright mention, but overlooked the trademark clause.

Please share an email with me if you would like to discuss further.

支持自定义皮肤

主要是这个转盘很影响判断，影响游戏体验
