Cosmic Cop / Gallop (cosmccop)

Shoot’em’up from Irem, which will later produce In the Hunt. And the resemblance is clear, from the design of your craft to the bosses.
The special mechanic there is the particle laser, that targets enemies automatically, but overheats, so you need to let it cool.

The game is brutal. One hit, and you’re done, the enemies can literally teleport on top of you, and the projectiles are fast and give you very little space to maneuver. I am not good in those kind of games, to be clear.

I found that the second boss is much easier than the first one. But then just getting to the 3rd boss was a struggle to me.
