Cubicle Commotion

This game is an entry for TweetTweetJam 6 and contains just 557 characters of code, small enough to fit in 2 tweets.

How to play:

Use the left and right arrow keys to hop from corner to corner and catch the flying red squares. If you miss one you lose one of your 10 chances. Catch 10 squares to gain an extra chance. Press Enter to start a new game.

Cubicle Commotion was written in Ruby with DragonRuby Game Toolkit. I had valuable help from the DragonRuby Discord community, especially Levi and Mooff.
