Great, the download works now! 1.6 GB is way too much for a tiny game jam entry, though. I don't know the ins and out's of UE, but that's something you really should have a look at. I'm guessing you are shipping the entire starter kit instead of just the stuff you are using in the game.

I did try it out and I like the atmosphere and the Resident Evil 2 vibe with the camera, shadows and the scary enemies. It's particularly cool that the shadows of the enemies are very helpful gameplay wise!

The controls felt really weird to me, because they are somewhat like car controls, but for a character and mixed with the mouse for turning. This would be the first order of business in my opinion: Fix the character controller. Basically copy the controls of any sensible twin stick shooter and you are golden.
