(in David Attenborough voice) "The life on the North Pole is not an easy one. Scientists suspect, that the ever-present mysterious puzzles stimulated penguins' brain development, causing what some are now calling "The Madagascar Effect"... Wait, is this one wearing a bandanna?"
Jokes aside, the penguin theme is super cute, you've got a fun puzzle progression, which made me think (and start over) a couple times. The music is also wholesome - gets a little repetitive with time, but still pleasant. I liked the level design too and I've had a fun couple moments pondering about the solution and making penguin noises. I think I've managed to break the mechanic a little - it's possible to push the box perpendicularly while sliding on ice, I don't know if it was intended. Overall: had fun :)
