Friday Night Funkin - Philadelphia Excellent Philly Nice but harder is a free online rhythm game mod at fnf.gosprunki.net. This mod takes the classic Philly Nice song and cranks up the difficulty. The soundtrack is also available on Newgrounds. The creator celebrates reaching 1000 views with a “let's go!!!!”
The High Score system is a bit broken, so players are encouraged to comment their scores. Credits go to @Meekaryo for the chart maker and @AwezomeXD for Vector Traces (the creator admits tracing the icons and arrows).
For better performance, use the Turbowarp link: www.turbowarp.org/534237710. Controls: Use arrow keys. You may need to click the green flag multiple times to get the audio synced properly, and you might want to scroll down for the full view.
If keybinds accidentally change to something like DFJK, go to options, then keybind, and select the top preset (arrow keys) to fix it.
