I feel like the difficulty spikes a lot after that first level, like when you have a swarm of enemies, the unhittable ones become shields for the target you're supposed to hit.
The artist would be happy, thank you! We've decided to keep the difficulty and the chances of getting swarmed as a part of the game design, and that's why we also call it a Puzzle Shooter :)
Anyway, I hope that did not ruin your gameplay experience!
Brave choice, I also noticed this mechanic nad personally I do not share it because it makes the game extremely difficult after the first attempt, it should perhaps have been activated through a setting.
