My god is this not well done. Big props to you guys.
Art & Music: The use of the pixel perfect camera and the unity particle system is masterful in this, adding a lot to the atmosphere with the never-quite fully legible yet horrifying monsters and abstract symbols. Small nitpicks would be that the main character is a bit stiff, and that some of the UI feels less polished than the rest of the game, but you get used to it. The small worm enemies are sometimes too hard to distinguish from grass, especially when you're moving fast. The music is also varied, catchy, and pairs well with each environment.
Story: A slow burn that builds until a great turning point that hooks you completely and integrates well into gameplay. It's straight to the point and gives you a sense of greater unknown powers at work. The simplest things like the location name give you lots of intrigue by itself. One thing I think that could use more work in a longer game is to give more characters and attachment to the townspeople, though that may lengthen the intro a bit too much. Perhaps focusing on one or two characters and really endearing yourself to them would make the impact that much better. Right now they are funny and varied, but I haven't spent enough time with them to remember them much or our main character.
Gameplay: The movement is oh so satisfying and easy to control. I'm not sure I found out what to do with the stone symbols, but there's a decent amount of content in this map. The spear's hitbox does feel a bit small so landing hits can be a bit hard to judge. I found myself tanking hits / avoiding enemies more than I tried to properly engage them, so it might be worth looking into making combat more fun? Not sure.
The levels are well crafted and have many small, interesting puzzles and challenges to do. Coming back between rooms was still fun and little nooks and crannies weren't too obvious but still easy to spot if you were looking for them. The game really opens up after the turning point and it feels exhilarating (which ties into the story well). There's a small issue where occasionally I can get tossed back and forth between level boundaries but it's mostly smooth.
That is to say, I am completely nitpicking and was blown away by your work. I enjoyed it immensely and will be following to see more progress!
