FNF Retrospecter is the toughest mixes and the most customizable play ever. Do you like struggling over the song? Or is your primary goal to listen to it to the end? Hell and Heaven difficulties are made just for both. Plus built-in modes like Freestyle, where you can click any arrows as far as you’re getting along with the beat, or No-Fail regime instead of the tutorial.
Moreover, it includes a randomizer that automatically creates a different chart for a song. Have fun toggling between rare-to-find functions!
