Answer 1

An enemy is just an object whose actions -or interaction with- may lead to a game over. For enemies to work here, you need a lose condition and a way to enforce the lose condition. There is no other concept for enemy you need right now. The way you will implement the enemy is by dealing damage to the player upon collision.

You must create:

1. A parent object which you will call obj_base_cat. It will have no sprite. Declare a create behavior setting something like vspeed = 5; damage = 0;. The damage variable is just to have it as defined.
2. A player object.
3. A child object of obj_base_cat, with the regular cat sprite. When creating, invoke super (the parent behavior), and also damage = 3;.
4. A child object of obj_base_cat, with the bomb-having cat sprite. When creating, invoke super (the parent behavior), and also damage = 3;.
5. The player, when receiving the collision of an obj_base_cat (children will trigger this condition as well!) will be hit given the .damage property of the cat. Then you must handle the criterion for damage reception, life loss, and eventual game over. If you don't do that beforehand, the whole concept of enemy is meaningless.
