Yeah, it is not surprising to be disappointed if you were looking for a challenge survival-wise.
The only Milestone shmup that actively enforces a harsher survival difficulty is Radirgy Noa because the only way to cancel bullets in that game is with the bomb which has to be recharged, unlike Chaos Field's windshield sweeper and ability to stay in Order Field, or Radirgy/Karous/Illvelo's shield. It may sound good in theory but the result is a game that's not as fun because you have to learn when to use the bomb to stand a chance in later levels and if you deviate from the timing, you're likely fucked.
When trying to score, Milestone shmups can become very frantic, especially near the end. Getting the sword to level 50 in Karous means you can gleefully slash the fuck out of everything, Radirgy's later stages are a non-stop extravaganza of bombing and using the invincibility to slash as many ennemies as possible, and Illvelo's stage 5 can get very fast-paced when trying to quick-kill as many mid-bosses as possible with the detachable modules to cash-in the key multiplier accumulated all throughout the run.

Oh yeah, I never thought about that, but that can play a big role in why Milestone's shmups are niche even here. Their games' atmosphere are the polar opposite of something like Thunder Force.
