This is a game I created with 2 other students for Mozilla's Game On competition. It works best in Chrome or Safari, but is generally playable in Firefox 4. If you sign up for an account, you can make your own levels and share your levels page with anyone!

I really like the look and feel of the game, kudos! I am, however, struggling to manage two players at once. Is it meant to be played by two people on a single keyboard? Are any of the levels single-player?

Yeah, it's meant to be a two-player game. It's really tough to play alone! We're looking into networked play, though we can't modify the live site while the Game On judging is in progress.

That explains why I thought the game was so hard :)

I feel that the experience of controlling both robots was very interesting though. The split-screen behavior worked very nicely for that.

This is amazing, that you're able to maintain 60 fps for all the madness that is going on. Good luck!!

The performance is quite good. Is the source (the unminified version) available anywhere?

Yes, it's open source on Github: https://github.com/evanw/rapt

This project is far and away the best thing to ever come out of CS32 at Brown. The HTML5 version is more than enough forgiveness for neglecting to to reply to the e-mail I sent you on May 18, 2010. ;)

It's pretty great, though if I had a Solaris box handy I might pit it against the networked multiplayer Zelda game a CS32 team wrote in '97. ;-)

That sounds awesome, and it came way before Four Swords!

You're right, we never responded, sorry! We appreciated your e-mail, and your wish has (finally) come true: the JS version is open-source.

Feel of the game is very similar to this Ninja game (http://games1.org/flash-games/NGame) done in flash. Its amazing how much can now be done in HTML itself.

For anyone wondering, this is "N" by Metanet software[1] (remember the developer name, as the game is impossible to Google). There's a paid version on XBLA, personally I prefer keyboard controls.

You seem to need to play each level twice, which is kind of annoying. I eventually made it 150% through the first level, then closed the tab.

I probably would have kept playing if there was a single player version.

Nice physics. The WASD control is unplayable in a dvorak mapping, though. I had to give up on the first level.

I like it. Performs well and it's entertaining. Although I must admit I have some difficulty getting my right and left hand to accurately control both characters at the same time. That's not so much an issue with the game as it is with my lacking motor control though.

That's good :) I'm playing with Javascript gaming/coding at the moment, so this is very educational. Thanks.

Some single player gaming would be great, although huddling round the keyboard is very (very) social :-)

Totally awesome. HTML5 rocks
