Putting together a working FPS in a jam timeframe never fails to impress me! I've tried that, it's hard... This had some nice touches of polish, like the animation when picking up oil / power. The factory disappearing as time passed was also very cool!
One feedback for the mechanic of throwing drones with balls - it's almost impossibly hard without an aiming mechanism of some sort. A simple reticle in the middle of the screen would help a lot, but since this is a robot an estimated trajectory line might even make sense. Also once you throw and miss it's usually very hard to find a ball again - might've been nice to make that a collectible as well (like ammo).
I scored 7720 - no idea if that's good or bad, but the game left me wanting to find out what happens to the young robot next.
