A stranger knocked on his door one night to break the news that the evil queen had declared magic illegal. Not good news for a sorcerer, as you can imagine.

Spunk and Moxie is a one touch platform game by Tilt Studios that relies on split-second timing and perfect reactions. It's a game of extremely high difficulty and no room for error, as the slightest little mishap will send you back to the beginning of the stage. That may not sound like a terrible punishment, but Spunk and Moxie is about high scores and unlockables, not raw level progression, so anything less than a perfect run is just not satisfactory.

And so comes 8-bit Halloween, an arcade platform game that borrows from some of the most popular sidescrolling games of old to create a challenging, holiday appropriate release to get you in the mood.

Inspired by a retro game? Check! Precision platforming tactics? Check! Melt-your-eyes gorgeous visuals? That's a check! It looks like we have another heavy-hitting indie game on our hands!

A simple errand takes a turn for the surreal when our hero, forced away from the video game console and out of the house, stumbles down a hole into the middle of the earth where he is, of course, tasked with tracking down magical gems. The same thing happened to me the other day. A little bit retro, mixed with a healthy dose of metroidvania and high-difficulty platforming, and Kodachrome is a weird but appealing little challenge.

Poor, helpless little... what are those again? Squished hippopotamus faces? Circle-blobs? Yeah, those. Poor helpless those. Actually, at least one of those circle-blobs has a name: Mayhem. And as you play this little genetically engineered experiment in OneSmartBunny's action/platform game Project: Mayhem, you'll begin to pity these critters more and more. But then you'll realize how tough this game is and start focusing on what really matters: landing jumps that require almost pixel-perfect execution, all without slowing down to see what you're doing. Good luck with that!

Bitless by Nicholas Rapp is like Space is Key meeting up with a platformer. It's a tough but funny, unforgiving but strangely compelling arcade game you play simply by tapping the screen. You'll be mocked by the narrator, you'll be tricked into messing up, and you'll die more times than you'll admit, but you'll keep playing simply because you can. And because you must. Getting hooked on Bitless is almost like acing an exam just because your friends said you couldn't do it. That'll teach them to spout mildly non-supportive jargon at us!

Based on the B-movie of the same name, the one famously riffed by the Mystery Science Theater 3000 crew so many glorious years ago, MANOS - The Hands of Fate is a retro-styled platform game from FreakZone that may very well be as punishing as the film itself. In a different sort of way. Armed with a few guns and an impending sense of "doom", work your way through the game's enemy-infested levels in an attempt to best your own speedruns. The Master would be pleased if you got a high score.

I Wanna Be The Guy was a small indie platform game released way back in 2007, and if you're wondering what took it so long to get a sequel, you obviously never played the original. A quick refresher: you could be killed by falling apples. You could be killed by apples that fall upwards. If you avoided the apples, a cloud could drop out of the background... and kill you. And that would be how you got past one screen. The sequel ups the insanity and makes you wonder if you really do want to be the guy.

Back in 2005, Takumi Naramura released a retro-styled exploration game called La-Mulana. Starring an archaeologist professor named Lemeza, it introduced modern players to an aesthetic not seen since the days of the MSX home computer, bringing with it all the convoluted puzzles, items, and high level of difficulty retro gamers love. Fast forward to 2012 for the worldwide release of a graphically enhanced update to La-Mulana that carefully reworks the look and feel of the old game to spruce it up for a new audience.

Oh no! The king of the realm needs you to save the princess from the evil clutches of the Dark Knight! Go figure, right? Wind-up Knight is a mobile run and jump adventure very similar to Canabalt HD except you get a fancy sword and armor to fight enemies while dodging traps to make your way to the princess. Convenient items in adventuring, yes, but it won't save you when the Dark Knight starts getting really serious about stopping you. A knight's mettle will never be more tested and neither shall your timing skills as pits, enemies, and environmental dangers stand in your way.

A lonely, lost robot wakes up to find itself floating towards a strange island. It has no memory of where it came from or what it's doing, but as the little raft touches stable ground, it does what any amnesiac creature might do: runs forward to see what's out there. Gear World may not be the most original concept this side of Cave Story, but the hyper-difficult platforming action and carefully designed levels more than make up for the conventional setting.

Platform games commonly require a fair amount of jumping to move around, but the author of this unique platformer decided that jumping is the new walking.

Ziggy Fraud will never learn, at least not as long as he can bend reality to his will in weird ways and his noble chicken steed is there to carry him from danger!

Raise your hand if you've heard this one before: The evil Dr. Mad has corrupted the programming of six thematic robots and has sent them out to do his bidding, each utilizing a weapon that would be suspiciously effectively against exactly of their evil kin. The only thing possibly standing in Mad's way is the new creation of the good Dr. Thane: the high-jumping, fast-dashing, laser-blasting, ability-stealing Rokko Chan! Okay, Japanese developer King admittedly isn't exactly trying to hide the inspirations for his retro platformer. But if Rokko Chan may look and play like a ROM hack, then it is a very lovingly crafted one of high quality.

Imagine if And Yet It Moves with smooth world tilting instead of 90 degree shifts, and instead of being a little dude, you're a little ball, so your big choices are to rotate one way or another way, except you also have a fire charge skill and you can stick to walls and you can shoot lightning and also drag scenery... yeah, Sideroller throws a lot of puzzle platform mayhem at you very quickly, but that just makes it more fun.
