Hey Paxtian, congrats on submitting your first game jam title!
I like the setting, clear goal, and the music fits well.
Controls: I don't have a controller ready and found the keyboard controls difficult to use. As a desktop gamer, I am more used to aiming with my mouse or WASD/Arrows to be relative to the character, not absolute directions in the world.
Level design: the rooms were too big / empty for my taste. Sometimes I would have very little reference to decide where to move towards.
Camera: I don't know why, but playing felt a bit nauseating to me. I think it jittered a bit sometimes, maybe. Not sure.
Weapons: I like the choice of gun & grenade. Maybe the player could control how far the grenade would be thrown? Would be nice to maybe throw a grenade into a room, bounce it off a wall towards an enemy without risking to stand in line of sight.
Overall the game could still feel a bit juicier. But very solid first submission. Keep it up, mate!
