🥳 We did it!

DOOM Captcha become TOP 1 Product of the Day on Product Hunt, thank you!

This is Crazy! I had the idea this Friday, developed the first version on Saturday morning, published that night and went live here on Sunday.

I think that today there have been much better projects than this one, but somehow DOOM Captcha has brought you some kind of nostalgia and you felt the project as yours.

I'd like to continue my career as a creative developer, so you all gave me a little more confidence in me, if you loved this I'd like you to check out my projects as well.

Thank you all for your welcome and comments, I hope you enjoyed it, had a few laughs and it made you want to play DOOM again.

❤️ Update 2021-05-26: John Carmack (Doom creator) liked it.
