General info: each player choses 2 habitats and gain 2 copies of each basic card from those habitats (20 card decks). The first habitat you select will be your main habitat and gives you its corresponding Leader Order. They each cost a different amount of food which is gained by placing your bugs in the backline (the column closest to the edge of the screen). At the start of your turn, your bugs attack. But if they are in the backlines, they instead gather food equal to their strength. Just like hearthstone you gain mana or "Energy" each turn and gain more and more after each turn. For cards and food meters you can hover over them to get some info on the card / order effect and any keywords it includes
