Yeah, I'm having some issues with this running on itch for some reason. I reached out to staff for help, so I gotta wait & hear back.
In the meantime, feel free to try out a rough & outdated version at: tweetdungeon.now.sh
It's basically the same game, just with a few missing features. If you'd like, I can ping you when these problems are resolved so you can play here :^)
