Do you take your retro gaming seriously? Like, 1990 isn't actually retro seriously? Then you're in for a welcome bit of news: the 1983 classic Lode Runner has been ported to Android (yes, it's legit / authorized).
The classic puzzle platformer has been on iOS for some time, but is just now landing on our OS of choice. Unfortunately, I can't vouch for just how committed the port is - the developer couldn't even be bothered to generate Android-specific screenshots, and that's rarely a good omen. However, given the size of the app (24MB), and the 15 minute return window, trying it out for a few minutes before you commit to giving up your hard-earned $3 for good is certainly feasible.
The app package name suggests this is actually a port based on the Game Boy version (though the description says it's 'true' to the Apple II experience), if that's relevant to you. Some modernizing has been tossed in as well, like customizable controls, the ability to alter the color of the worlds, and online leaderboards.
Head over to the Play Store to check it out.
