I have been working on new obstacles (such as these turrets), and I intend to introduce most obstacles in a fair manner, for the player to be aware of their mechanics before properly encountering them;

As shown in this video, the turrets will not be able to fire directly at the player right away, allowing the player to learn various things about the turret, such as the fact their bullets won't go through structures, and that their trajectory is fixed to a specific location, all of this in preparation for future challenges.
