hello osamahussein, thanks for playing my game and thanks for the compliments.
I know than the collisions are a crap, and it was for my low knowledge of godot than it give some problems, and between work and personal time I couldn´t do more, they have two different type of nodes for the enemys collision (one attack and other been attacked), if I make one little, the other one should be little to, and the same in reverse, I thought than it would be better hit the enemies far than receive from close, but actually i think than it was a stupid idea
