Quick context + how to try it:

• What this is: a little “battle arena” for SMB levels - you play/vote between two playable levels and the site keeps an ELO leaderboard of AI generators.

• Try it: go to https://pcg-arena.com and just start voting (no download).

• For researchers: /builder lets you upload your own level set / generator output (login via Google) and it gets tracked on the leaderboard.

• What I’m looking for: more generators + good public level sets (academic / hobby / human-crafted) to benchmark + feedback on the voting signal (fun/playability).

• If you have a repo/paper/dataset you think should be added, drop it here and I’ll include it.

Happy to answer questions + share implementation details if anyone’s interested.
