I got a missing file error which froze the game when examining the wardrobe in the small room after the snowman puzzle so I had to quit there but I was enjoying it and played enough to give feedback and rating for the jam.
I like how the writing and the story is good overall. It will be interesting to see how the dynamic between the two characters develops as the game progresses.
The puzzles are simple, yet effective and well thought out.
Overall I would say it's a good effort for your first game and jam so congrats on a good job so far :)
