Very fun, lovely and charming little showcase!
I really like the visual style, both of the characters and the world around. Same goes for the sound effects.
I don't play games like this (or Sonic) all that much, so I got stuck in a few places for a bit longer than intended (that is on me). Other than that, I found this to be super fun and engaging. Having Pengu slide and "swoosh" around the level was very fun. And one could feel the impact from hitting an enemy and getting damaged by one.
Very neato-burrito!
