Cool game! It is simple but you can always add more content to it . I love the mechanics of preparing the cones in advance, having two of them waiting in the "production line" and then only adding the topping on it when a penguin shows up. If you add more machines, different types of cones/toppings, and have like multiple penguins showing up at the same time it will be pretty fun to manage your little snow cone shop!
Good job!
