Cool use of the limitation! Attacking has the chance to hurt you, but you are forced (or, I assume that needs to be the case) to attack enemies, which is good.
I did find a bug - the enemies don't seem to harm you, which gives the player the option to just not shoot at all. When I did shoot, it was sometimes a little unclear if I would be hit by unseen drones, which felt a bit unfair at times. You do have enough health to compensate for those moments, though!
The lab setting you have created is also quite nice!
