Well executed! I liked the concept and the sprite art was cute. I'm a sucker for penguins. Good choice of music and it's impressive the sound effects don't interrupt the background track. Overall good puzzle design. I had a few "aha" moments, especially on level 10. Level 12 was great. The reward screen after level 8 was my favorite. I do wish the art style of the reward images was a bit more consistent. I'm assuming that's a result of the use of AI generation. Also, level 4 seemed harder than it should have been. Maybe would fit better later in the order. Great job on the whole!
