FNF Mr Fun Computer Test is this weird little rhythm mod that came out in 2025. It’s part of the Friday Night Funkin’ fan scene, but instead of battling a person or monster, you’re up against this glitchy computer guy named Mr Fun. The whole thing feels like your screen’s about to crash any second. The colors flash, random windows pop up, and the music keeps getting more distorted the longer you play. It’s honestly a mix of funny and stressful in a good way.
It is exactly what you expect. You hit the arrow keys (or tap if you’re on mobile) when the notes slide up. Timing’s super important mess up too many times, and Mr Fun starts glitching out the game even more. The beats are quick, and the background keeps throwing distractions at you, so it’s a lot of focus and rhythm at once.
A cool detail is how the devs leaned into that computer test idea. There are fake system errors, fake restarts, and weird voice lines that sound like a corrupted assistant trying to talk to you. It kind of plays with your head a bit. The songs are all short but catchy in that crunchy, digital way like they were made on a broken synth.
