Thanks for playing and the recording. You caught some bugs I didn't know about.
The screen-clear, seems too strong currently. It's mean to be a beginner plane perk that gives a new player free kills, to propel him forward. And for stronger player it offers kamikaze attack if he has spare lives.
But now I think it might not be good for new players to relay on this gimmick, because it doesn't teach them how to play properly. I think I might move this to some plane that's unlocked later into the game.
