5.5 Special thanks
A huge thank you to Grok from X. Although Hearts Major Version 2 is based on version 1.9.6, which I developed entirely myself, 
this new version is a complete overhaul and was programmed with the help of Grok's AI. 
It allowed me to generate code, especially for animations, debug, get explanations, translate some text, and made many valuable suggestions. 
This version would never have seen the light of day without Grok.
