thanks for playing and your feedback . I was watching a play trough of castle Vania 3 and say the implementation for hearts as a means to have ammo for a special weapon, and implemented the gems ad the kunai was supposed to be a sub weapon, but I could not get my melee attack to work, so i left it at that, I do agree that loosing gems and not being able to shoot slowed the game so I decided to have the green bats drop 3 gems if they hit the player or if the player shoots them. there is still so much that I have to learn thanks for your feedback .
