No lite version but it is priced at 0.99 for the first few weeks at least. If you liked Flight Control and Real Time Strategy games then I think you'll enjoy it.
Looks like lighthouse hd is fairly similar...well in principle anyway. Hope this still releases tomorrow
Released in New Zealand and coming to the US in a few hours - along with a short "mood" trailer. I've only seen the Lighthouse gameplay trailer but The Blitz is totally different. Simply put it is a Flight Control RTS.
It's out! I'd provide the iTunes link but I'm doing this from my iPad and lazy. http://appshopper.com/games/the-blitz-hd
