Long time was past from the last roguelike dev update, but the game is still in work and today i can show you some of the cards design and the deck management directly as you see it in the game engine! This are the cards relative at the battery and hp restore.

The “USE COST” is the amount of battery needed to play that card.

The “MAINT COST” is the amount of battery needed when the card is in the deck, pay that amount every turn.
