A bit of feedback: please don't rotate the puzzle piece for me! A huge part of sorting out where a piece goes is figuring out its orientation in space and if you tell em automatically, I miss out on that whole part of the process, and suddenly all the pieces are sorted for me.
This looks fun! One question, your terms mention payments, but I couldn't find any paid content in my short session. What is the business model? Is there a pricing page?
Good question and sorry for the confusion! I originally launched with an optional paid tier which I have since removed. Currently there is no business model. I happily run this at a loss as my costs are very low.
