This is so fun, creative, and well-polished! The central mechanic is super genius - one simple action, lots of considerations with the way the penguins move and the iceberg interrupts. I love how much the gameplay escalates as you keep going--but you get benefits as more penguins get on from the 1-2 connecting "stops". If I have one suggestion, it would be that it's very frustrating to lose a penguin when you're sliding the platform the opposite direction, and slows down the pace of the game - I wonder if once a penguin gets on, they could automatically stay with the platform in the center / get pulled to the center and stay there until their destination is connected, meaning you could switch around a lot faster. Still though, very fun and nicely done!
