The concept of this game is wonderful in my opinion. And I did enjoy the execution, as well. There are some things that I do feel could improve, however: primarily one of the characters (and some of the writing). If I'm honest, it's Anita who ruined a teeny bit of the experience of this game for me. I didn't think she was funny in any way. I feel that she's based on stereotypes and while making her obnoxious was clearly your intention, she just feels so incredibly, incredibly bland. Of course, what small part of the game I played through only makes up a fraction of the finished product, so I can only hope that things change up a little for her.
Besides that, I have to say, for the one character with a dark(er) skintone to be dressed the most revealing (like, near nude revealing, especially in contrast to the meek, almost prudish, milk-white female protagonist)... it's not a surprise at this point for WOC to be portrayed as promiscuous, but still. While it is something you probably did not think about, and while it is probably not your intention to offend anyone, I would suggest reading up on the fetishization of women and men of color in games.
Moving on from my least favorite character, the writing, to be clear, was not bad. At all. I did enjoy the narrator (especially the overworked one's) comments, I thought he was relatable and in short, one of the funniest bits of the game. However, the at one point overdone references to a quest and the characters being members of a party annoyed me to no extent.
In short, Hellevator I would say has great potential. Great potential. It has its strong sides, its weaker ones (as does every game). I do have to praiseJack! He's a demonic child whom I love for some reason, but then again I do tend to root for the weird (if not somewhat evil) characters. As such, I like Mary, too, because she is most definitely a cultist. (Not even her last name, Goodman, can convince me she isn't.) I am (perhaps a little impatiently) looking forward to any updates to come for this game. I'm curious as to how the story will continue and how the characters will develop (if they do so).
That being said, please stay healthy and safe, and finally, thank you for making this demo (aaaaand for making Jack... pls don't let him die)!
