Hi! Thank you for playing and for the precious feedback. Yes, the enemies follow a movement order. When designing the levels I always kept in mind a "move hierarchy", for examples goblins move always first, or gnomes move last (with the player exception). In theory, if nothing strange happens, all levels work this way.
I wanted to implement a list that showed which enemy moves first, second, third... etc, but as I didn't have much time I preferred to polish more "critical" parts of the game. As for the last level, it was intended that it could be possible to block the enemies (as a hidden shortcut), but I think you are right when you say that I should have said/shown to keep an eye on the enemy movement, and I understand that you felt it was a bug. If I'll choose to expand upon this game idea, I will keep this in mind. Thank you!
Regarding the movement speed in the later levels I agree that the movement speed can feel slow. In hindsight I could have added a x2 speed button or something similiar.
