There were thing like goblin and zombie spawners in the early days of developing this game. When I completed my second game I forgot that I was suppose to make them. But I think I can use this idea in the sequel (RPG game like Zelda 2 nes).
I can minimize the down time of golem just enough so we can pass him. I originally planned to make an animation where it shatters after dying and comes back to life with those pieces. But I'm not that good at animating just yet.
I didn't meant them to be actual assassins, just the ones that are annoying and can keep up with you over few cliffs. Giving them feature like climbing rope would require me understand path finding (which I plan to understand for my next games)
I not very good at programming. I can only promise things if I have a vision on how to achieve them.
