- I had 7 days to make a multiplayer Backrooms horror game in a $1,000 game dev competition… despite the fact that I do not make horror games (and I definitely don’t enjoy being scared)

In this devlog, I build a cursed ’80s synthwave backrooms arcade in Unity, wire up proximity voice chat, dynamic lighting, a flashlight system, a janky-but-fun interaction loop (pick up / throw / yeet everything), and a scent-based enemy AI for Flopsy... the creepiest bunny mascot you’ve ever seen. Then the judges play it…
If you like Backrooms, FNAF / Poppy Playtime vibes, fast-paced dev breakdowns, and chaotic multiplayer moments-this one’s for you.
