13 Games in ≤ 13kB of JavaScript · js13kGames 2018

As the seventh annual js13kGames competition comes to a close, a grand total of 274 games were submitted. Even more impressive, each one was created in a single month, using less than 13 kB.

We rounded up a few of our favorites featuring a number of different styles and genres. From dark shooters and pixelated beat ‘em ups to perplexing puzzle and platform games—enjoy some downtime this weekend and play them all (or fork and hack on them with your own customizations)!

UNDERRUN

UNDERRUN is a twin, stick shooter “in 256 shades of brown,” using webGL from @phoboslab. In this game, you must defend yourself from predators while figuring out how to restore power to fix all system failures. Sounds simple enough, right? See for yourself when you play this highly-addictive shooter (and enjoy the haunting music). Read more about how the game was created in the retrospective.

Envisionator

@DennisBengs created the challenging puzzle game, Envisionator. The goal of the game is to escape a building on lockdown by giving a robot commands. What’s the catch? The robot needs you to give it each and every direction, step by step—one false move, and…well, you’ll see! Play Envisionater to see if you can escape.

ONOFF

Things aren’t as black and white as they appear in ONOFF. Dodge spikes, jump over pits, and toggle between dimensions. Think you can overcome each level of traps? You’re in for a treat with this mind-boggling, fast-paced platformer from @starzonmyarmz and @braddunbar. Play it to see what we mean!

The Chroma Incident

The Chroma Incident by @Rybar is also a twin, stick shooter but with a few more colors than UNDERRUN. The problem is the color’s been stolen by the Achromats, and it’s up to you to bring it back. Shoot your way through areas to reclaim those colors—give it a go!

1024 moves

Not to be confused with 2048(!), 1024 Moves is a polished puzzle game from @GregPeck. Get the ball, and avoid the holes—what’s the catch? See if you can solve the entire game in less than 1,024 moves. Play and test your problem-solving skills.

Spacecraft

@tricsi’s Spacecraft challenges you to collect as many data tokens as possible from the planets and moons of the Solar System. It’s easy—until gravity accelerates your ship, and you have to avoid obstacles along the way in, “space, the final frontier.” How far can you go before your probe goes offline? The only way to find out is to play on.

Off the line

How are your gaming reflexes? You’ll quickly find out when you jump Off the Line to collect coins in this arcade tapper from @regularkid. Take your time to figure out the best way to collect coins, or go crazy with a timed, ultra difficult ULTRA MEGA MODE (if you’re feeling lucky). Play it and see how many coins you can collect.
