Thank you so much for this in depth review!
Yes, the recipe board was not good enough. It was a time thing. Every chain should have had it's own (circular) board showing all the recipes with better rendered icons that will be easy to follow. I agree with basically everything that you wrote down.
So so glad you liked it! We have the feeling that this can be expanded on a lot with more items, different effects and even different cubes! (3x3x3 and more)
