Pink is safe

Made with 547 chars of Pico-8 for the TweetTweetJam.

Use arrow keys to keep Pink on its safe zone and bring him back to his blue island. Then level number will increment, safe zone will be a bit thinner, shorter, faster, and everything will have to be done again, oh no!

Here's the complete program, ready to copy & paste to your favorite Pico-8 console :
