Reminds me a bit of the doom variant that would kill a random process for each enemy you killed.

  There's also this arcade-style shooter which kills a random file for each enemy. A bit riskier. http://www.stfj.net/art/2009/loselose/ http://www.stfj.net/art/2009/loselose/

You probably want to make it more clear that you're supposed to mouse over the dark lollipops and avoid the blue trees. I assumed the dark chars were the walls I shouldn't touch and just about gave up on it after it was constantly crashing. Then I read the description after the fold and figured it out. Also why not just implement the game in javascript using mouse position events and a canvas for drawing?
- szhu 11y ago
  Dark lollipops? Blue trees? What operating system are you using? I'm on a Mac and the lollipops are pink and the trees dark green. I'm considering making a text-only version for people who have weird or no emoji support. Of course I could implement the game in javascript, with nice graphics and all, and perhaps gameplay that works in all browsers and doesn't crash Chrome, but wouldn't that defeat the point of the game? :) Happy to take PRs though!
  - staz 11y ago
    I'm on Chromium on Ubuntu. Also have Dark lollipops and Blue trees, guest it depends on the font or something. https://imgur.com/Ffc3zcx https://imgur.com/Ffc3zcx
    - tdicola 11y ago
      Yep, on Ubuntu here too and it's exactly like that.
    - szhu 11y ago
      When was the last time you've had a black lollipop? Or seen a blue tree? Thanks, Ubuntu. Anyway fixed! The the instructions reads "Mouse your way through the map without touching the /trees/!"
      - vacri 11y ago
        It's not ubuntu's fault. Ubuntu/FF here, and I'm getting green trees in FF, blue in Chromium. Blue trees can be seen in mountainscapes in certain light conditions. Or in the Blue Mountain... well, the trees themselves aren't blue, but they're covered in a blue haze... but still, the emoji is evergreen_tree...

Amazing. I always love seeing these sorts of harmless, fun ways that bring attention to these strange edge/corner case bugs.

  Funnily enough, opening this url gives a GitHub Server Error.

You know you've been working with ASCII for a long time when you can automatically unescape the title... and then pause, considering whether to unescape again. I think reading the comments on that bug is also rather enlightening; points of note include a 62-level-deep stack trace, comments to the effect of "we don't know what the bug is/how this is supposed to work", and discussions about whether escaping multiple times is the solution (absolutely not!) https://tools.ietf.org/html/rfc3986#section-2.4 https://tools.ietf.org/html/rfc3986#section-2.4 Implementations must not percent-encode or decode the same string more than once, as decoding an already decoded string might lead to misinterpreting a percent data octet as the beginning of a percent-encoding, or vice versa in the case of percent-encoding an already percent-encoded string. Seriously, I'm quite surprised that basic URL handling is still a problem. Making a game to bring this to the attention of a wider audience is certainly a good idea.

  Reading the bug report: https://code.google.com/p/chromium/issues/detail?id=533361 https://code.google.com/p/chromium/issues/detail?id=533361 makes me sad. Recursing is definitely not the answer, yet it gets brought up a lot. Also, %00 shouldn't cause the browser to crash, and the fixes suggested so far are just work-arounds :/
  - username223 11y ago
    > Recursing is definitely not the answer, yet it gets brought up a lot. Speaking as someone with an apostrophe in his name, I'm not sure whether this makes me want to chuckle and reach for the popcorn, or bang my head against the desk. The answer to multiple (un-)escaping bugs is never recursion.
- aaggarwal 11y ago
  It's surprising that this issue was brought up multiple times as a bug, but wasn't taken seriously until it got special attention. This bug is definitely notorious, I wonder setting a similar URL as the homepage of Chrome will cause Chrome to continuously crash and make it useless.
fidz 11y ago
This is a beautiful experiment. To OP: i wonder, how did you find this bug?
- szhu 11y ago
  It's actually all over the news right now: https://www.google.com/search?q=chrome+url+bug https://www.google.com/search?q=chrome+url+bug I found it because someone posted about it in a school Facebook group I am in.

This works in Chrome on Android as well. Of course it's way easier than on desktop.

The game doesn't "work" on microsoft edge but the brower doesnt recognize the Stanford links[0] , it is not possible to copy them by right clicking. Going directly to the page by copy/pasting the url doesn't even load the website. IE doesn't seem to understand the url as well. The only brower I've tried that manages to get a page is firefox[1] [0]http://www.stanford.edu/%%30%30 http://www.stanford.edu/%%30%30 [1]http://i.imgur.com/nEDgBrq.png http://i.imgur.com/nEDgBrq.png
