Thank you for your feedback! Funny enough with the "all-seeing entity" you suggested. I was originally going to make the story of the game involve a person on the outside of an old television constantly hitting the different buttons on a VCR player to mess with the player himself. You would see the fingers of the person about to hit the buttons to give a warning of when time is about to change, and to constantly remind the player of who the villain of this game is. The ending would have involved the player-character angrily walking towards the screen of the TV, he would then jump out of the slot of the VCR player and tackle the person who has been trying to get the player killed the whole time. The screen would then cut to black, and then to a picture of the person with his head shoved into the slot of the VCR player.
I also like the suggestion of having smaller enemies that would reverse time somehow, I'll have to think of a way to incorporate a design of an enemy to fit that purpose.
This is some very unique feedback, I appreciate it so much! I'll be sure to check out your game in a bit!
