I agree with everything in the comment below. The game is super fun, a quite big sequence with manageable difficulty but only one life was a nice change of pace, the sequences are all different and the unstability of the enemies is something you're able to react to by keeping your distance so it's a fun twist.
I dislike that the bullets of the enemy are hard to distinguish through yours. Also the life of the boss could probably have been lower to me as with one life it seems legit to take the time to position yourselves to shoot it only when you're sure you won't get hit, it was specially relevant with the 3rd pattern (not the 2nd one but the 1st one too). It's only my opinion and these are small details, overall the game is pretty good.
