Simple concept but executed well and a fun challenge!
I did manage to get to the end of each maze on the first try, so you could have maybe increased the difficulty by a small amount. I liked the first person perspective and controls were smooth but sprinting felt a bit weird as if my character kept speeding up and slowing down. I think the animations showing the path through the maze were extremely well done, not too fast (so you can't keep up with the turns) and not too slow, so that you start forgetting them again.
The main menu music fit the concept of the game well but I was missing some in-game music too (preferably something relaxing that doesn't distract the player's concentration). Very nice use of sound effects though.
I think there are plenty of ways you could expand on this idea, for instance by putting traps in the mazes! It was already very cool that there was a freeze time pickup, maybe you could come up with other pickups as well (like XRAY for instance or something like that?). Nice textures on the ground but some textures for the maze walls would have been nice!
