Favourite game I've played thus far. The switch mechanic and puzzles are well done and you do a good job teaching how to use them before increasing complexity. Chefs kiss for the Fox craw animation.
The puzzles are well done, but the elements are missing some color or feature differentiation. I couldn't tell the difference between blocks that couldn't be destroyed by the bear and ones that could. Also, the level and values needed to be play tested a bit more. I donked myself into the ceiling repeatedly because of the high jump and low ceiling.
Overall, really fun game that looked great and played well. You also hit the theme pretty well.
