The "Solo Star" badge should definitely be a hard badge, IMO. I have been playing this game for two and a half hours and I always blow up in the sky on Level 16. ALWAYS! :( Still a fun game, though, even if slightly frustrating at time. Only complaint I have is what has already been said about blowing up in the sky. 4/5
