This is a submission for the DEV April Fools Challenge
What I Built
I built Bug Hunter, a Chrome extension that spawns crawling bugs on top of real websites so you can "debug" them by smashing them.
It solves absolutely nothing in real life, which makes it perfect for this challenge.
Open any page, start Bug Hunter, pick a tool, and hunt.
Smash bugs to lower your stress meter and boost score.
Miss too many and the page becomes a full-blown infestation.
Delightfully useless? Yes.
Strangely therapeutic? Also yes.

I built Bug Hunter to be immediately funny, fast to try, and fun enough to replay for a "higher score + lower stress" run.

If this made you laugh, react/comment so more people can discover this beautifully unnecessary extension.
