Heyy MasterSushi! So the 'shift' to look ahead feature is used to scout ahead for enemies that may be off-screen, including turrets that can shoot at you from afar the moment they detect you.
Yes! I made the enemies kinda scary when they chase you, to add a bit of a challenge to the game, I'm glad you like it!
I thought of making it completely dark, and you'd have to use a flashlight or the burst of your gun to see, but the game became too difficult, but that's definitely an idea I had and I might implement it in a future game, so thank you!
Yes, I can make it more difficult!
Thank you for your comment! I'll definitely add more levels in a future update!
