Thanks so much for the feedback! I'll definitely take a look at the difficulty on the harder puzzles. Also, I will be sure to make it so you cannot break the shovel in Level 2 before you have repaired it. The hint book should make things easier, as I can use that to point the player towards the correct place.
I'm not sure why the steps counter was still in place on level 5, did you shoot the bell with a bow and arrow to end the counting?
Also, if you'd like to continue, the way to finish level 5 is to parkour to the top of the crumbling tower after jumping there from the unlocked square one, then shift down through the snow to find the key.
Thanks for playing!!
