Amazingly polished game, well done! I loved the intro, the visuals and sound design were great and the gameplay was fun. There is nothing to criticize. I liked that there were meaningful pickups. Congratulations on your first Game Jam!
I played the game with a controller. Even though it is not supported in the menus, it seems that Unreal’s input system makes it possible to play the game with it and it felt more natural for me than the keyboard.
Oh and great job with the page for the game as well. I love the humor. :)
