A boss should feel like the end of a mission, not just a larger target. Recent IRIDIUM 33 playtests have focused on giving each guardian its own silhouette and attack rhythm, with clear warnings before the hardest moments.
We have also spent time on the feel of the smaller moments: a hit that has weight, an explosion that reads at a glance, and controls that keep up when the screen gets busy on iPhone. We are still adjusting difficulty across the full campaign so the challenge builds without sudden unfair spikes.
