    Haha, this is nice. I'm bad at regex most of the time. Playing this felt like when I first switched from Visual Studio to Vim. it’s a bit of a learning curve. It’s an interactive game btw

    Every vibe coded site is too dark and the text is too small.

      And not playtested at all :D
    • mchaver 1 hour ago
      I could envision the style even before clicking on the site.
    • mdp 3 hours ago
      This is fair, although I ask for it to be dark themed to match what I think was the style of typing game I remember growing up with (it's been a while). Bumped up the font though.

        Next time please ask it to respect system dark/light mode preference, it's trivial to do, especially for an LLM which can spin up light/dark alternatives easily.
        • NooneAtAll3 1 hour ago
          no

          considering free windows being light theme only, it should be a button, not a "system default"

          • xnorswap 54 minutes ago
            There should be a button too, but it's simple to add a line so that it also defaults to any provided preference.

            That's fine, too. Either way, give the user the choice.

        My top complaint is that if I've successfully used a pattern, I want my text removed. I keep forgetting to backspace a bunch, then get frustrated that my pattern isn't working.

        Other than that, great game!

      Maybe because it 1337 hackerman-style, or something.
    • christoph-heiss 3 hours ago
      And all the text is grey-on-grey and basically unreadable. Not to even mention accessibility.

      They all have this rounded box design as well. I wonder where that came from, I don't think it was a predominant style before.

        I vibe code web apps with Google's Gemini and I think it actually mimics Google's UI and UX because I see similarities between my vibe coded web apps and Google's web apps.
        • progbits 2 hours ago
          But that's a different style from the these colorful border rounded boxes that I think Claude in particular loves to produce.

      Every vibecoded site have this same dark look with shining hue-gradient borders, can't wait for the future the entire web be filled with this generic look
    • darkstar999 3 hours ago
      What evidence do you have that this is vibe coded?
      • flexagoon 2 hours ago
        Because it looks exactly the same and feels as janky as 99% of vibecoded web apps

    Nice game!

    We made a similar game several years ago for the Pyweek game competition, but there wasn't the fun "letter invaders" style that this one has.

    I really like your implementation!

    Might be good to limit some of the special operators to give more focus -- otherwise the early levels are a bit too solvable with ".*"

  • freedomben 4 hours ago
    Wow really cool! Genuinely fun, and educational at the same time.

    One usability request: after firing a regex, could the text box be cleared? It's not hard to hit Ctrl+A and start typing again, but it does add a bit of friction. (I can send a PR)

    I don't understand the first "combat" level. There's no real defining pattern separating the good from bad hex strings, so it's just a typing speed contest to type all the enemy patterns, right? What am I missing?
    • Andoryuuta 2 hours ago
      As far as I can tell, the first combat level enemies all start with "ALERT-" and have exactly 3 digits.
      • 1-more 1 hour ago
        sorry, second combat level. It's all 6 digit hex color strings, some good some bad.
        • Andoryuuta 1 hour ago
          Ah, I see. Yeah, that one definitely took me multiple attempts to see what it wanted.

          I believe that the "enemies":

          1. Must start with "#"

          2. Must be exactly 6 hex digits

          3. Must be lowercase

          • 1-more 1 hour ago
            Ohhhhh I swore there were friendlies with lowercase too! Thank you!!
            • schiem 28 minutes ago
              There are, just not lowercase characters that are valid hex.
  • joshribakoff 2 hours ago
    I cant even read this because most of the text is outside my phones viewport. Please test your stuff before posting it here.

    I wish it wasn't time-limited...

    This looks like something I would vibe code with Google's Gemini. Interesting concept.

    This is really funny ;D Gives Tetris vibes and is executed beautifully.

    Fun interactive game!

    Cool idea! I shall give it a try :)

    TL;DR: I think you should still learn regex, even though AI has made it a "useless" skill

      Anecdotal data point, writing and maintaining regex is still a core part of my job. Not useless at all for me :)
    • m3galinux 4 hours ago
      Not so useless. In my experience LLMs are about 50/50 on making a regex that actually works and covers the cases you asked it for. Even less when you get into cases needing advanced features like backreferences and lookahead.
    • croes 4 hours ago
      A little bit early to tell.

      Let’s wait how affordable, available and good AI is when the companies turn to profit maximization and enshittification begins

        You can go local now with qwen 3.5 9B Q4 powering hermes agent at 35 to 50 tok/s with 99 percent tool call success rate on a used RTX 3060 for the price of two months of ChatGPT Pro and never bother. https://xcancel.com/sudoingX/status/2033020823846674546#m

        This is the worst local AI will ever be. It only gets better from here. https://xcancel.com/sudoingX/status/2033959603944493192#m

        • croes 47 minutes ago
          Nope, if nobody trains the models on new data you have at some point an outdated model.

          Imagine Qwen 3.5 created in the 1990s and then use it for today web or desktop development.

          And is the problem solved that training AI with AI code makes the AI worse? If not the "it only gets better" claim is questionable.
