Congratulations!
I was worried whether anyone would make it all the way through, since some puzzles required a bit of creative thinking. But you proved it's possible!!
I understand, as you said, that grasping the rules takes time, and that's where the challenge lies. I think adding hints or small interactions to guide players when they get stuck is feasible within the game design, so I'll consider it.
Thank you for the wonderful feedback.
It was a fantastic challenge!
(If we update it or expand it for a product release, I'll work hard to make sure you get at least a little bit of that “aha” moment next time :))
