by 16BitsOfAwesome - Compo Entry

Cow Duck Fever!


An endless runner where you can switch between a duck and a cow.​ Jump through as many hoops as you can!

Is your high score better than your friends? ;)

MY TOP SCORE IS CURRENTLY 90 :D. I seem to choke every time after that point lol

Space - Change between Cow or Duck


Click the game window if the buttons don't work.

A good twist of the flappy bird sub-genre. Congratulations!

Interesting concept, similar to flappy bird, but with some special touches.

as said in previous comments, similar to flappy bird, but I think I got frustrated even more. Really cute graphics!

Ha! This is great. The switch mechanic really adds fun reflex twister. I kept getting tripped up over two simple buttons. But I never got frustrated. Great job!

A nice twist on the flappy-bird formula. I liked how you had to determine when to jump as well as when to shapeshift to the different sized hitbox.

I wasn't a big fan of not having any control over the height of my jump, I think it would be nicer to be able to jump higher depending on how long I hold down the jump button.

Graphics were lacking a bit, but communicated the mechanics well. Good use of the theme.

Well done!

Thanks for trying our game out and the heads up! Sorry about the white squares, we've exported the same version but with an installer that should run better (give it another try hint hint). Otherwise, I'm team duck all the way! -t

Really neat game! I included it in my video compilation series of Ludum Dare games, if you’d like to check them out :)

Hi, nice game ! We're realizing a video with several games of the Ludum Dare #35.
Can you add your game on ? (it's free)
So we can include also your game in the video ;)
p.s. write #LDJAM in the game's description

It's an okay game. Good job.

Good game. The graphics worked, but your speed should ramp up as you progress, often we found ourselves jumping too early or too late, there's definitely a sweet spot between falling like a rock onto the poles and jumping into them too late.

About as hard as Flappy Bird. Still a well built game.

Cute game! I disagree that a cow can jump higher than a duck but that's just details ;)

Da Duck is Dense AF

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.
