Absolutely love it. Unusual captcha's are great. Reminded me of this one: http://random.irb.hr/signup.php

I remember an old (and now defunct) fan site who hit you with lore questions as a captcha. Though I'd guess a LLM could answer

Who else is clicking "click to start" like me? It turns out you have to choose one of the buttons. I thought they are there to allow me to enable/disable the sound, but they also both act as start buttons. Didn't know a simple interface with a sound switch and a game start button can be designed this badly.

Yeah it doesn't even need the option IMHO, I don't think sound is needed here...

E1M1 is absolutely a part of the experience.

> Don't take this too seriously, this is a little project for fun, if do you know how to code it's pretty easy to break the security of this.

As opposed to standard "click the traffic light" type captchas which are almost impossible for modern AI to break.

I think the doom captcha is probably more secure than standard captchas simply by virtue of its obscurity.

You should try for a full 3D implementation of Doom! I'm sure it's been ported to JavaScript at least a dozen times.

Wny stop there when you could just use a webassembly port of the actual game with hacked-in portal to the actual site somewhere... :P

Who else is missing the forest for the trees? It turns out you have to focus on the merit of the contribution instead of inconsequential UI design optimization. Didn’t know a simple demo (with disclaimers) from someone who is clearly doing something novel could be commented on this badly.

> inconsequential UI design optimization

I tapped "click to start" on my phone a few times, saw nothing happened and assumed it didn't work on mobile and tapped back to come read the comments. I am neuroatypical, though, maybe I don't count as human.

Earlier quoted context omitted.

Wow, that's pretty impressive to me and I think it's awesome that you were able to put this together quickly. I admit that I don't have a CV background, so maybe this is easier for a programmer who's already experienced in that area.

To be fair I don't think you need CV in this specific case where the problem space is very limited. 1. There's no lighting, so the enemies have specific, fixed pixel colours that don't appear in any of the backgrounds. Scan and target these. 2. Enemies appear in a specific zone in the canvas. Makes scan faster, combines with below. If there's expected ambiguity one can a. detect a few interesting background propertie…

Nah, a proper anecdote should end with 'and you could check a one checkbox at the gov site and instead of the scan you would receive the 'printed' PDF/A with the text layer intact'.

But yeah, there is always a way to optimize. Even if making a clean room implementation (ie not looking at the source of that DOOM captcha) you can easily narrow down a recognition to a couple of 2x2 blocks and just pattern match them against a known background (ie not a monster).
