The fact that this is a 3D game made for a game jam is already an incredible achievement on its own! Congratulations to the team for the effort put into that aspect, as it really stands out compared to the majority of jam games, which are usually 2D.
I also have to say that I absolutely loved the atmosphere. To me, it felt unique and fantastic. From the ground to the sky and the background scenery, every detail was interesting to look at. The only thing that felt slightly out of place were the markers on the ground, but I don't consider that a negative point since they serve an important purpose for the golem's attacks. In games, readability is often much more important than pure aesthetics.
Speaking of the golem, I found its attacks quite interesting. Even though there weren't many variations, the fight still managed to stay engaging throughout. It was fun to see the enemy evolve after each defeat. There was one moment when it got stuck against a wall though, haha, and I was able to finish it off pretty easily because of that.
I didn't encounter any major issues during gameplay, but I did feel that my mouse sensitivity was extremely high, even when I set it to the lowest possible value in the settings menu. I'm not sure whether that's something related to my computer or perhaps the web version of the game. Another small thing I would suggest is having the weapon automatically reload when the magazine is empty and the player presses the fire button. Right now, after running out of ammo, you have to press R every time, which slightly interrupts the frantic pace of the action. It's just a minor detail, but I think it could subconsciously make the combat flow feel even smoother and more exciting.
Overall, I think the team did an excellent job. Both the visual design and the audio design were wonderful. The voice acting fit the game very well, and it's easy to see the care and effort that went into this project. Congratulations to everyone involved, and I wish you the best of luck in the jam!
