Roguelike Simulator
About
NetHack is an incredible game. And an incredible pain in the ass. It took me like 200 deaths to beat it once. I have a trophy to prove it. No, really.
People nowadays don't have the time to learn a game about dying in spectacularly embarrassing ways. But fear not — I have taken the full NetHack experience and condensed it into only a few minutes.
Can you navigate the dungeon and get out alive? Probably.
Made in less than a day with bitsy, a very tiny tool for making very tiny games!

I don't have the source code anywhere separate, but I think you can just upload the HTML file back into the bitsy editor.
