This is a neat idea! I like that the game has you navigating two kings of puzzles simultaneously, between solving the mirror puzzle and navigating the maze. I had fun!
Here's some constructive criticism, if you'd like it:
- I assume the ZQSD controls are intended for a different keyboard format than what I have. Unfortunately the WASD controls did not work for me, which made it very difficult to play on my QWERTY keyboard.
- It wasn't immediately clear to me that the maze under the ice was supposed to be a reflection of a hidden maze above the ice. Now that I realize that, I do think it's cool you incorporated the reflection element in this way, and I think it's a fun idea. However, it took me a bit of time to realize why I couldn't walk across, so it may be good to consider how you can make it more clear to the player what the maze is supposed to represent.
- I felt that the anime aesthetic for the player characters was a little disjointed with the stylized low-poly environment (this may just be a personal preference, but thought it was worth mentioning)
Overall, I thought this was a creative concept and had fun solving the puzzle. I think you did a good job with the cozy winter vibes (and I appreciated the cinematic camera angles at the end)! With some more polish I would definitely play more of a game like this.
