Do use a normal zip file incase anyone decides to try this on something else that isn't Windows through Proton or Wine.
Anyways!
Yeah the Unreal Engine really does make this look gorgeous especially at 1440p, but the it's weird discrepancy with the relative level of detail of the engine/lighting and the sparseness of the levels.
The instant grid movement seems to have motion blur for some reason? Which I'm sure is just due to the way the Unreal Engine works by default, it's a little disorienting.
Also I agree with @graphicsmismatch, the game does not run very well and the motion blur does not do it any favors... I have a similar setup to @graphicsmismatch.
Enemies appear to only die when their animation finishes, and if firing repeatedly at an enemy they will restart their death animation.
There is also that interesting issue of the player and enemies not obeying the same rules but it's pretty easy to kill the enemies so as long as you're paying attention it's not super difficult.
