Gotcha, I didn't add the invincible to the character because with the spears they give you range attack. They can also destroy the projectiles from enemies that attack with projectiles. I did this purposely to make it a challenge but not impossible but also different for a 2D game. As far as the attack goes you can attack again by clicking again. Unless you mean you want different attack animations. Did you beat all the levels? Thank you for your feedback.
