Sky Force from Infinite Dreams isn't a new game by any means. I remember playing it several years ago on my Windows Pocket PC. So when I saw they had ported it over to the Droid I was quite happy. I immediately downloaded a copy and it plays just as well as it did back then. Sky Force is a great mobile game.
Some of the comments I've read state correctly that this is a port of a game from 2005 and it hasn't been upgraded. True. So is Pac Man. That doesn't mean it's not fun and not a worthwhile addition to a game library. Sky Force is a blast to play (no pun intended) and I'm glad to see another esteemed mobile developer support the Droid (and I'm sorry, but this game is specifically for the Droid). So if vertical scrollers are up your alley and you have a Droid pick this one up... you won't be sorry.
