UNDO Academy is a creative institution that focuses on art and animation, and many of their graduates become game artists and developers. VORT3X was approached to design their 2025 Chinese New Year packets, featuring their Ctrl + Z mascots called ‘UNDO zais’ running through a side-scrolling video game level. The series of 3 festive packets features 3 Chinese idioms, all of which are visually supported by relevant illustrations. The 3 festive packets can be combined to form an infinitely continuous graphic, making it a highly collectible and fun set.

A looped greeting animation was also created for the purpose of sharing on social media and messenger apps.
