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).

The API is back! Thank you so much to @tgr.bsky.social and others who worked so hard standing it back up! What this means:

* Wizulus's level viewer (smm2.wizul.us) should be functional again for all levels that are either in cache or not deleted
* OCW import should be functional again

also by clankk, not technically a single comment, but the first in a set of stamps he's made for displaying mario maker 2's stamp comments on our website!
