This is a very simple artstyle but with your lighting it makes it look so elegant. The gameplay is extremely simple and easy to understand, and I like how you sort of "eased" the player into the game. The puzzles were very well designed as well, you really made me think about what to do. The movement is tight and everything just makes sense. The music also helps to accomplish the dream aesthetic, and you really got the atmosphere of a relaxing game going.
I barely have any thing to suggest, but all I'd say is that maybe you could have introduced some more mechanics as the player proceeded through the levels. But you were under a time restraint so I can understand if you wanted to add more originally.
This is a solid submission, I really hope this continues to do well in the jam!
