this engine its not very good and its on demo/beta/testing but if you want an FNF engine that its playable, you can use SSS! (Scratch's Smooth Saturday) its perfect if you want to make an FNF mod in scratch, the coding its perfect, i seriously dont know how someone made this project ALONE, but someone did. check it out! Link: https://scratch.mit.edu/projects/609230073 here you can found some mods that were made with SSS https://scratch.mit.edu/studios/32759507/ im not finishing this i think it has a lot of bugs, i made a list: 1. the engine cant handle spammy songs, search inside and create a spammy chart, and you'll find out why 2. bf/player cant sing at the start of the song, it can only sing after 1.329 secs after the music started 3. super small reaction time to hit notes 4. if you find, tell me
