It just felt very systematic, like the turrets were always trained on you. It felt a little unfair so my suggestion is to break up thie enemies firing/ aiming a bit (cool downs, ammo count then reload) would make it more fair possibly.

It's true that the ennemis that fire bullets don't have different behaviours we could work on that. I'm a bit sad the other types of ennemis come so late because I think they have more fun patterns that perhaps would feel more fair. We have one that behaves like the dvd logo and bounces on the edges of the screen firing some bullets and leaving a trail. We have one that teleports every few seconds and fires a missile on the player frequently that explodes and releases bullets. We also have one that doesn't shoot bullets but gives a preview then moves quickly towards the player (inspered by sans lasers from undertale).
