Wow I really like the art style / shader. I actually feel like Thor, when I throw the briefcase out and summon it back.
The game itself is really fun, although making it easier could be more enjoyable. My suggestion would be:
1. A bit of aim assist. Throwing in VR sucks, giving the player some assist like pistol whip (aiming in the general direction would result in a hit) can make it easier (and more of a "superhero" feeling).
2. Some indication for drone spawning. I recon that there's some sound effect for it, but something visual would be helpful. Also try to not spawn enemy behind the player when the player is fighting some other drones, that's really unfair to the player.
3. Fixed rotation when the briefcase is summoned back. Everytime when it's back it's in a weird rotation, and blocking the bullet is harder in that case. Maybe when you summon it back, make it in a "natural holding position" as you would hold a briefcase?
Anyway, great concept, and a fun game. Congrats on finishing such a polished piece of work. Oh and is 1350 a good score?
