Hey guys i've started work on an osu! port to HTML5, some of the features that will be in it upon release will be:
- All osu! standard beatmaps from desktop version will be playable
- Beatmap videos will play
- All skins for osu! will work with osu! uebu
- All beatmap-specific skins will work with osu! uebu
- asm.js core for speed (should run about only 1/16th slower or less than osu! desktop)
- WebGL, your html5 osu! will be GPU accelerated just like osu! desktop.
- Local storage of records/replays
- Multithreaded with WebWorkers so you can get even better performance.
- Other stuff i've yet to decide on.
- Support any microsoft browser.
- Support IOS Safari.
- Add Catch The Beat.
- Bancho connection (would need peppy's permission)
- Tycho mode
- osu! mania
- Javascript Video Codecs
- Beatmap editor
