Cool puzzle adventure ( no pun intended :p )
Your artstyle is really nice, and i like the limited palette choice, the music also felt quite fitting with the cold theme of the environement.
The wolf "soul projection" when you take a nap on the warm pads is a fun mechanic also :D
and i like how you explain the controls within the game for the restart and sleep actions.
If i had to nitpick i'd say the main issue i encountered is that sometimes the character gets a bit stuck while trying to fit through a 1 block large space, but other than that i didn't have any problem.
Good job :)
