This is a nice demoscene for your game. The Unreal Engine visuals are stunning! The way the audio of the announcement and music was nice, too. An audio or visual cue for when buttons (preferably both) were pressed would have been nice, as would a crosshair of some sort to indicate where you're aiming. The first time I loaded the game I got softlocked by dying from falling outside of the map from the missing wall on the opposite side. Good job getting shooting, a shooting enemy, and button functionality working in the timeframe in a 3D game (especially if I remember right saying that you didn't have unreal engine experience)!
