Hey! I saw your post on reddit a while ago! I think though that removing the sign in would definitely be nice for less bounce as others on reddit said. Otherwise i I think it's fun!
If you'd like to we can talk or mention eachother's project on our site to get a backlink and also to help noobs (like me, haha) go back and forth, because I think having a cheatsheet and somewhere to practice also could be fun and the audience might be interested in one-another! You can add me on Discord under "pici_csomi" if you want to talk :)
