The Sunstone is an ancient technology that helped Vikings to navigate in a cloudy day. You only need to know the time of the day (by the position of the Sun, sunrise or sunset) and the Sunstone will find the Sun in the cloud sky. With those two informations (the position of the Sun and if it is after sunrise or before sunset), you can determine the cardinal direction.

To make this things simple I assumed that the sunrise is always on EAST and sunset always on WEST.

More info in this video:


You have 5 minutes (300 seconds) to earn as much points as you can by finding the objective location and delivery goods in the island. You will be rewarded with an option to upgrade your ship speed or a bonus added to the score. Each good delivery gives you 10 points.

- Tap or click on screen to move the ship

In the screen you have the following information:
- You distance from the center of the screen
- The Sun position (sunrise or sunset)
- Your objective, saying the cardinal direction you should go and how far it is
- The time count down
- Your current score

You also have two buttons:
- Reload, to load a new objective (bottom left button)
- Sunstone, to open the sunstone and find the Sun location (bottom right button)

Using the Sunstone:
- There are two black dots in the Sunstone, when both have the same intensity (see screenshot 2), there is the Sun
- Based on the Sun location (sunrise or sunset), you can determine if the Sun is pointing to EAST (sunrise) or WEST (sunset)
- That will be enough for you to find NORTH and SOUTH

Some observations:
- The Sun position and Sunstone are reset each time you reload or delivery the goods in an island
- If you get lost, got back to the center of the sea and try again
- After some time is possible to go to other locations without going back to the center


This game was developed using cocos2d-x V3.12 and C/C++ in a Mac OS X environment (that's why the Windows build will come later, I'm sorry about that). I used Photoshop for the art, and unfortunately I had no time to create background music or sound effects.

===== BUILDS

- The Android version was tested on a Moto G (version 5.1)
- The Mac build was tested on a Mac OS X El Capitan 10.11.6
- The Windows build will come later


Thank you for playing my game (and read this description). Please, let me know if you found problems or if the instructions here are not clear about the gameplay. I didn't have time to work on music, sound effects, menu and few options like restart the game.

I liked the idea of using a sunstone to go through the scenario, very interesting concept for game navigation! I got confused sometimes though, I that kind of person that get lost with directions. :)

Great game, congrats!

I also made a viking-themed game, but my technologies were brewing (already ancient at the time) and longships (new then, ancient now).

Your game has a lot of boring downtime while you sail into whatever direction towards the current goal

The Game is really hard to understand at first, you should really put an instruction text in there.

Mini Submission FAQ

TEAMS: Teams entering the Jam should pick a single representative to submit your game, or create a team specific account you can share. We currently do not support Team Voting, but sharing an account and together playing and rating games is acceptable.

CAN I ENTER BOTH EVENTS?: You should pick 1 event, whichever you think it’ll do better in. If the idea is strong, and everything plays well enough, you can go Compo. If you’re a perfectionist, and would prefer people to play a more polished game, do the Jam. Many solo participants enter the Jam.

If you made 2 games, unfortunately, the website doesn’t support multiple submissions per user. To submit your 2nd game, you will have to make a 2nd account. Only do this if you made 2 games. Alternatively, if one game is better than the other, then consider just entering the better game.

CAN I KEEP WORKING UNTIL THE DEADLINE?: Yes! Immediately after the 48 or 72 hours, we do something called Submission Hour. As the name suggests, it’s an extra hour for you to package, upload, and submit your games. If there were catastrophic issues trying submitting your game, or you misunderstood how submissions work, that’s okay. It happens. We’re flexible. If you need advice, check with the folks on IRC. If you need an admin, get in touch.

CAN I KEEP WORKING ON MY GAME?: Oh definitely! You should! But for the sake of judging, keep the Compo or Jam version around. You can include a link to the Post-Compo/Post-Jam version of your game on your games page, but sure your main links are the original version.

PORTS: Ports to other platforms can be done after the deadline. That said, the sooner you finish your port, the sooner people can play your game, improving your chances of placing in the final results. For best results, provide a Web version of your game, or a Windows version with no dependencies. Also be sure to rate at least 20 games to improve your visibility (Coolness).

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crashes, win condition, or tiny bugs after the deadline. In a sense, this is like “porting” to support more players. We leave this open to interpretation, but generally speaking your game should be identical to the game you submitted. No new features, just fixing mistakes you should have caught had you been better rested.

MY GAME DOESN’T SHOW UP: If you can’t find your game, it’s usually because the URL to your downloads are missing ‘http://‘. Fix your URLs ( and you will show up. Alternatively, if you just posted it, wait a minute. The cache may not have refreshed yet.

NOT LOGGED IN?: If you get a message about not being logged in, even though you are, it’s because your web browser cached the non-logged in page. You can fix this by either refreshing your cache or clearing your cache. CTRL+F5 in many browsers. Chrome is a bit more work. Press F12 to enable Developer Mode, then you can right click on the refresh button and select “Empty Cache and Hard Reload”. This option is unavailable if you are not in Developer Mode.
