This game is wild. I see two mechanics at play here: the shadow knight that's following your steps, and the perpendicular laser between you and the shadow. You put these two things together to create a gimmick that's really creative and super fun to play with, so top points for that. The graphics looks really nice and I like the time stop mechanic, this game would be impossible without it. I also like how you indicate the speed of time with those top and bottom black bars, it's a really nice touch.
I think the game could be a little easier, though. My biggest issue are the enemies that look like pots, because they seem to change direction at random when you hit them. It makes them difficult to predict and dodge, even with the time stopping. The ghosts could also be a little slower, I had a hard time outrunning those. You could trim down the number of enemies on the second-to-last level, I often found myself getting cornered by them with no way to move.
Overall though, amazing game. I beat all the levels and had a lot of fun playing through it. You owe me a treasure now :D
