Wrap up

You have another game under your belt, and I hope your brain is already starting to bubble up ideas for things you can do to improve it. Plus, you learned more skills, not least SKCropNode, SKTexture, GCD's asyncAfter(), plus lots of new SKAction types, so it's all time well spent.

Try experimenting with the difficulty and see what you come up with – is it easier or harder if the penguin show/hide animation happens at random speeds?

Review what you learned

Anyone can sit through a tutorial, but it takes actual work to remember what was taught. It’s my job to make sure you take as much from these tutorials as possible, so I’ve prepared a short review to help you check your learning.

Challenge

One of the best ways to learn is to write your own code as often as possible, so here are three ways you should try your new knowledge to make sure you fully understand what’s going on:

1. Record your own voice saying "Game over!" and have it play when the game ends.
2. When showing “Game Over” add an SKLabelNode showing their final score.
3. Use SKEmitterNode to create a smoke-like effect when penguins are hit, and a separate mud-like effect when they go into or come out of a hole.

Share your success!

One of the most effective motivators of success is sharing your progress with other people – when you tell folks what you're doing and what you've learned, it encourages you to come back for more, which in turn will help you reach your app development goals faster.

So, now that you've done all the hard work it's time to share your success: tell folks that you've completed this project, either by clicking the button below to start composing a tweet, or by writing your own message from scratch. This will definitely encourage you to keep learning, but it will also help other folks discover my work – thank you!
