The style is absolutely adorable and is one of the cutest things i've seen and heard in a while.
I usually can't stomach sokoban and other games of that kind, but this one was an exception. It didn't feel overwhelming and puzzles were just hard enough.
But, to be honest, in the end it was getting pretty boring with all the running around, trying to figure everything out.
Amazing job otherwise.
Edit: Forgot to add, but i think it deserves to be pointed out: i would legit buy this game on some steam sale and play it to 100%.
