I saw that @Deimos had made a post about the history of Chex Quest about this game in 2019, and since it has been over 6 years since then, and I felt the urge to play it again, I figured I'd see if anyone else had any memories of this game.

My dad brought a copy of this home with him one day from work that he got from a coworker whose kids enjoyed it. My brother and I played it a solid amount and it was an awesome game, and also my first exposure to a game that ran in the Doom engine. I also had a distinct memory of seeing the game play of the original Doom for the first time and thinking "hey that looks like Chex Quest!".

Chex Quest is a shareware title so you're able to download the files and play the game for free. I can't remember where I got them, but I have the first three Chex Quest games as .wad files that I was playing with Chocolate Doom. There are also fan made .wad files in the Chex Quest style that I've yet to play, but maybe one day! I even remember there being a Doom randomizer that included the ability to generate random Chex Quest levels, but I can't seem to find it while doing some quick searching online.
Edit: I found the random level generator a few minutes after posting this: https://github.com/obsidian-level-maker/Obsidian

They also released a Chex Quest HD on Steam that I remember got me to go back and play the original game 5 years ago.
