Gameplay

What is the difference against osu! ?

  • Some slidertypes may not have support yet.
  • Free access to pseudo-osu!direct service (is an osu!supporter feature in osu!).
  • Dynamic Main Menu background based on the current song's background (can be disabled; is an osu!supporter feature in osu!).
  • May need to change the Music Offset value if hit objects are out of sync.
  • opsu! allows any beatmaps to forcefully use a predefined "Difficulty Settings" set in the Options sidebar.
  • opsu! has about the same amount of Game Modifiers (in-progress) to osu!.

For Android players

  • More faithful to osu!.
    • opsu! Desktop is almost the same as opsu! Android.
  • For a small screen (4-inch and below) or having difficulty reading the user interface, the user interface can be scaled in the options screen under Extras;UI Scale.
    • In doubt, use the left side of the screen for scrolling.
      • Absolute Scrolling (right-click to speedscroll the scrollbar exactly to the cursor location by top-down distance) is disabled here.
  • No support for video in Android port, yet.

Questions

Is there a beatmap specially made for opsu! ?

Any beatmap that is made for original osu! is also made for opsu!.

There are no beatmaps created specifically for opsu!.

I have many beatmaps in T-Aiko...

Cut and paste all the beatmaps to opsu/Songs manually using the device's File Explorer or equivalent.

Unconfirmed note: T-Aiko is unable to use mnt/sdcard/opsu/Songs directory for some reason (it gives unknown error [T-Aiko]).

Why is the default skin different?

All osu! graphic and other game assets are copyright ppy Pty Ltd. [...] You are NOT permitted to use these graphics outside of skins and/or beatmaps. This includes using them on other websites, games, products etc.

opsu! in Google Store?

A direct rip of fluddokt version as per mentioned in itdelatrisu issue #346 and fluddokt issue #232. itdelatrisu stated to not care as long as it does not violate the GPL license and fluddokt has not given a response as time of writing (24/12/2017, Christmas Eve).

The source of concern can be based on lack of same licensing (specifically, GPL-3.0), the commit history itself, the README.md not crediting fluddokt since it is based on fluddokt fork, and the unprofessional response to user Turquoise2_ regarding the "Loading" error faced rather than an attempt to actually fix it.

Consider downloading from official website releases for now rather than Google Play version whenever possible.
