Glad you enjoyed the visuals :), my main department are graphics and I'm trying to also get better at gameplay feel. There are a few small (free)props that I also used because I just didn't have the time to model literally everything but the scenes/structures were made from scratch, every texture made by me(except for some in the final maze).
And yes, I didn't have time to code the ending but right now I'm updating the game and make it to be some kind of a demo. Not sure if I'll make a full game with this story but will defenetly use this art style :). If you'd like, you can subscribe to my channel , right now I'm working on a personal project with a similar art style, but rather than just being a walking simulator, it'll be a FPS shooter.
