The art and movement of the penguins and seafood was so cute, so good!
The fact that new enemies were added as you progressed and the number of enemies increased as you progressed was very similar to the thrill of going down a hierarchy in a roguelike and facing an unknown enemy and trying to win a game that you don't know if you can win or not.
I thought it was amazing that you could express this so well without the concept of level-up elements, equipment, etc.!
Thanks for a fun piece!
