I like the term "reverse minesweeper".
As for the battery concept.... why did you gave me this idea ! :) Now I keep thinking about it and don't know which concept would be more fun. I think I'll create both concept and get feedback on both.
- The E automatically goes in the battery and player click on the weapon.
- Player click on the E and it fills up the selected weapon.
Maybe you had the item that gives +1 to energy. But I'll definitely have to up the healing. In the past, the enemy were hitting for 1 damage.
Great feedback, thanks a lot!
