Hello Tess,
Thank you for your reply, and thank you for explaining how you feel about it. I completely understand your point, and in hindsight I should have asked first before building my version around your puzzle idea.
Just to clarify, my project is a different game called Connection. It contains four (very simple) levels that I designed myself, inspired by the core mechanic of your puzzle, and the fifth bonus level is your original Let's All Hold Hands puzzle as a tribute to its creator.
I always include credits in both the source code and the game itself, and I will credit the puzzle design to beekie, with a link to your itch.io page exactly as you requested.
Thank you again for your understanding, and best wishes with your future games.
