You get five lives. One replenishes every minute. You can also get extra lives by winning tournaments against friends, getting a high weekly score and not playing for a couple of days. I'm not sure on exact prices but you can get various amounts of lives for various prices.They range between around €3 & €30. I haven't spent any money though. I'm trying to do it without spending money.
I don't think you can leave it idle. They patched in a stats screen but it only started counting from then. I played about an hour in the last week or two. You could just keep tapping the play button to add a minute but the game is freemium so you only have a certain amount of lives before you have to wait or pay to play.
PS1 support would be nice, but I own mostly physical discs. Metal Gear Solid is my only digital PS1 game.
I got that free game The Treasures of Montezuma Blitz. The trophies are mostly luck based and require 100 hours of investment so it's an annoying list. The trophies don't sync to PSN either. The Vita apparently needs a firmware update before the game can sync.
You have to pretty much win everything from now on. There was talk of augmented reality support that never made the release date which was rumoured to be DLC. I think it was just supposed to be a ship viewer so I doubt they'd add trophies to it should they release it.
