Rail Snake

by AuthorX - Jam Entry

Unfinished prototype for Ludum Dare 33. Inspired by the book Railsea, which I was listening to on audiobook for the week before LD33, The Beast from esteemed gaslamp fantasy webcomic Girl Genius, and obviously classic computer game Snake.

Originally the plan was to eat other trains to grow, while switching rails to avoid collisions. You can switch rails by clicking the circles. At the moment, trains will not interact but the snake will grow automatically every 10 seconds, as well as increase speed up to a maximum (there is no maximum to the number of snake segments, so don't leave it running if you don't want it to keep slowly eating memory).

The rails are randomly generated each time, so refresh or close and reopen to see a different configuration. Another plan was to set them along bezier curves, which I was able to do, but normalizing the speed along the curves would have been a whole other mathematical adventure and the cars were too erratic without it, so I went back to straight lines while I tried to get the rest of the features in.

I will probably not finish this, as I've decided that even if I got all features in, it would require a lot more work to balance the rail generation and collision chance to a playable state, and may not be particularly fun even then.

points for what looks like the start of an original idea.

Nice attempt, I think I see where it was going. It's a shame it wasn't able to be finished.

The web version runs on the first try, that is more then some got done,

The more you do the easier and faster it becomes to get what you want done.

It gets crazy fast, wish you could've made it further on this, would've liked to have tried the finished product.

It's a shame you didn't manage to finish this on time and probably never will in the future because that idea seems to have a lot of potential.

Could make an awesome mobile game! Nice work!

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. Historically, more games are entered in the Compo, but with more people and more time, Jam games have the potential to be better (that doesn’t mean they are). Many solo participants do 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.
