Make a web-based build of Appel with a different replay code system (change the letters or sum) and then upload it to itch.io. It can't be modified, and all replays have to come from it.

A fun place to hang out and chat about Appel, share your levels, learn to speedrun, etc.

I made an Appel subreddit (https://reddit.com/r/appelscratch), just so everyone knows. Can't advertise on Scratch so thought this would be good to let people know about it.
