总的来说，是个比较耐玩的游戏，当然，也需要你足够的耐心去摸索英文为主的菜单，虽然好像能选中文语言，不过遗憾的还是有大量的英文内容需要理解。如果你玩osu!,也最好有耐心去弄明白配置文件Configuration.json。
故事模式感觉时给小朋友玩的，龙的形象真心有点幼稚，不过好在有自由模式，我也只玩自由模式.
这个虽然付费，但确实比McOSU多出了一些选择，比如可以关闭滑块（slider)和旋转动作（spinner). 因此，玩起来更加随心所欲。
可玩性也好些，可以选择角色avatar。可以使用tracker用脚踢，这个挺好的，有助于提高运动量。
不过感觉可完善的地方还很多，感觉最急需改进的：
1.自由模式下角色还不能保存，下次进入还需要重新设置。看了下论坛，2018年developer就说会改进，不过貌似现在仍然不行。希望能早点完成。
2.osu等网上资源在我这儿下载很慢，所以我通常都下载到本地后在玩。我已经设置osu! 的路径， 但在菜单上找不到本地音乐资源，貌似音乐选择时，没有一个选项只显示本地音乐。
3.对于vive震动有点夸张，手都麻了，需要一个调整震动的选项。目前，我是通过steamVR的手柄设置，关掉震动，才能接受，不过问题是手感确实又差了一些。
这些问题希望能得到开发者的支持，多谢。（可以接受英文回答，多谢！）
Translated by google:
In general, it is a more playable game. Of course, you also need to be patient enough to explore the English-based menu. Although it seems that you can choose the Chinese language, unfortunately there are still a lot of English content to understand. If you play osu !, it is best to have patience to figure out the configuration file Configuration.json.
Story mode feels like playing for children, the image of the dragon is really a bit naive, but fortunately there is free mode, I only play free mode.
Although this is paid, it does have some more options than McOSU, such as closing the slider (slider) and rotating action (spinner). Therefore, playing more freely.
Playability is also better, you can choose the character avatar. You can use the tracker to kick with your feet. This is good and helps to increase the amount of exercise.
However, there are still many areas that can be improved, and I feel the most urgent need for improvement:
1. The character cannot be saved in free mode, and you need to reset it when you enter next time. After reading the forum, the developer said that it will improve in 2018, but it seems that it still does not work now. Hope to finish it soon.
2. Online resources such as osu are slow to download here, so I usually download them to the local and play. I have set the path of osu !, but I cannot find the local music resource on the menu. It seems that when selecting music, there is no option to display local music only .
3. The vive vibration is a bit exaggerated, the hands are numb, and you need an option to adjust the vibration. At present, I use the steamVR handle setting to turn off the vibration to accept it, but the problem is that the feel is really worse.
I hope these questions can be supported by the developers, thank you. (An English answer is acceptable, thank you!)

Thank you for the feedback and including the Google Translation!
感谢您的反馈，包括Google翻译！
1. Do you mean the calibration of the Avatar? We did have a major improvement in this area in 2019: Now, when only using headset and controllers, you don't need calibration at all anymore. With trackers (e.g. for feet), it's a bit tricky because the trackers could be attached a little differently in each session, so using a stored calibration may give you trouble. But that's still something I'm hoping to add, anyways.
2. Did you find the Music Library settings? It's in this video: - there can select which sources should be shown in the library. For your situation, it's probably best to use "osu!: Holodance Songs Folder".
3. You can control the intensity of haptic feedback in "Finetune Gameplay", it's the first entry under "Guides and Feedback", called "Haptic Intensity", see also:
游戏是好游戏。。。节奏还不错，我超喜欢第二条龙！！问题指引太少了。。。free mode怎么玩啊。。。进去完全不开始，就只能站着，还是我等级不够吗?
-----------------
I mean that when I enter the free mode,I can't play maps from osu! .What I can do is standing and listening music.Does it because that my level is too low? The novice tutorial is too few.I don't totally understand how to play the game.
