Bomb Card

Left Click: on a cell to play the card.

R Key: to rotate the pattern.

You have a deck with 10 identical cards. The cost is represented by the gear, and the damage by the fire, as well as a pattern in the center that shows the area of effect always from the center. Each time the cost is fully paid, enemies take 1 point of damage.

When the cost is completed or there are no enemies on the board, the game moves to the next wave, and a random card in the deck is upgraded. This can reduce the cost, increase the damage, or add a new cell to the pattern.

With each wave, the number of enemies and their health will increase.
