First of all, thank you very much for your detailed feedback!
The dynamic deck creation works in such a way that when you beat pool 1, you'll unlock new power-ups, so that’s when you can customize your deck as you like.
In general, in the early access demo, you don’t have many options on what to click. You just put the 20 cards in your deck, choose the deck you’ve created, and play pool 1.
To place the correct ingredients in a dish, you select them with a left-click, raise the dish you want to add them to, and then simply click “serve.”
No, the color doesn’t need to match. The color of the ingredients is just there to help you distinguish them. For example, green is for vegetables, red is for meats, etc.
Again, thanks for trying it out!
