First Impressions:
-BGM and creepiness it gives is beauty.
-Main Menu is minimalist and well designed. I love the font you used.
-I'd love to have you lead me on for the first few mins of the game to make me understand the game better. I am not good at these type of games though.
Overall, the game is gorgeous and the idea is indeed interesting. Also, I'd like to know how you placed the water. I've never tried it maybe you know some kind of a tutorial.
If you have time, I'd like to hear you thoughts on my submission too!
