Loved the lighting effects and the look of the fog.
I also really liked how the story was told. Was sad when it ended, look forward to the rest of their adventures! :)
Climbing the bricks vertically like a ladder was a little odd. By the dialogue I was expecting a classic wall cling mechanic. But once I figured it out it wasn't too hard. If you ever revisit, maybe go with bricks with vines on them as the tile for this as that's the more universal symbol for 'tiles you can climb' in video-gamese.
Main character moves a bit slowly, jumps feel kind of stiff as a result.
But other than those minor quibbles, I really enjoyed it, great work! :)
