2. CUSTOM TAGS ARE HERE

OCW has shipped a new tag list, available in all languages that SMM2 supports. Huge thanks to our volunteer localizers. Now you can tag your level as Troll, Precision, Kaizo, Suffering, and more!

1. CORRUPT COURSES ARE NOW PLAYABLE

Corrupt courses are now fully uploadable and playable on OCW! Get ready for blocks containing doors, toads, stones, and plenty of other shenanigans!

(We do ask if you upload corrupt levels to please indicate as such and exclude them from endless mode).

Update: Atmosphère has been updated, but a number of things have changed on the backend that require significantly more work to fix. Thank you all for your patience!
Heads up: It looks like @tgr.bsky.social's MM2 API is down.

What this means for now:
* Level import is not working for levels that haven't been loaded in @wizulus.bsky.social's level viewer before
* The level viewer will not be able to show NSO levels that haven't loaded before

For safety reasons, we have never collected money from anyone and our team is entirely volunteer-run, so unfortunately we will have to wait for TGR to have some spare time. Thank you for your patience!

What should continue to work:

* Importing levels that have been loaded in the level viewer before
* Viewing OCW levels on the level viewer
* Playing levels on OCW
* Managing your levels on OCW
