Yes.. well, not.
If you were using linux you could do this
"ssh joshua@crawl.akrasiac.org"
password: joshua
So you could play crawl without having to download it, but, in windows you have to download a ssh client, with weights a lot more than the game itself.
this reminds me to..Well, someone mentioned a chaotic god in stone soup that likes to poison PCs on low health etc. I imagine the Joker god as a less evil version of this, with some characteristic ADOM humour thrown into the mix.
