1 - In the start screen, if your intention is to murder someone through blowing their eardrums, then you might be successful because the volume is just beyond loud on an otherwise very noisy genre of music, f you're wearing headphones, if not your walls just collapsed. Do you not realize you can set the volume of each file in the wav itself/cue file if you have one/ambience as well??
2 - The "Tutorial screen" is just plain ugly but at least it tells the controls. I'm curious as to if you did a level for it alone or something because given the stuff below, idk, sounds like it might.
3 - You left debug prints of the chaser's health on. Whether that was a lazy form of a health bar or couldn't bother to make one, it's still a negative point because it breaks whatever "immersion" this may have had.
4 - Is that serious a JPG quality image as the city background?
5 - Personally (this one is my personal opinion) I think it's just kind of silly that you need to turn around to shoot while running away. I've never played something like that, if you're being chased you usually don't need to bother about turning around to shoot, or to do the moving at all.
7 - Did you really left logs/manifest file in the folder?
8 - Was it really that hard to add an icon to the game and change the folder name instead of leaving it as WindowsNoEditor? At least you didn't zip the files without the folder, so there's that.
And finally, 9 - Really? 900mb? There was jack size optimization done on this...
All this said, you really need to go look at several tutorials of how to effectively make a game using UE4 because sorry not sorry, but this is just horrendous...
