First thought when starting a level: which planet do I nuke first?
Friendlies there? Don't worry! They have 2x the hp of ANY enemy unit! NUKE THEM ALL FROM ORBIT!
...and suddenly, it doesn't matter how many units you have; it just matters you have one left to nuke them with.
Is this game even fair? After about 5 minutes, I lost any bubble cover I had, and concurrently sand-bagged from one screen to another before it decided to ping-pong me between two screens. The homing ones didn't seem to affect my character at some point, but it didn't matter as they were slow and I could just shoot them. At one point collect bubbles didn't even work. You also move a bit fast, as I can hardly stay within a bubble, and losing all progress is frustrating as I'm trying to whittle down a large thing with no health and a peashooter. Are there bigger guns? That might help as enemies seem highly overpowered, come from all angles, and sometimes aren't even in the arena when I'm shooting. I've also been hit when there was no bullet around me. Rather frustrating game.
