Nitrome has a string of hits on Android. It seems with every release, they are trying something a little bit different, but strangely enough, totally within their ever unfolding wheel house. Their latest game Vault, is an endless runner, and it is downright fun to play. It isn’t easy, but when you string together several vaults, one right after the other, you feel pretty good about it. In short, it is worth a download to play.
