    Evil dice simulator 2014 : GOTY edition


    When you run the game for the first time, type anything but load.
    Also, do not place on desktop.

    Evil dice simulator 2014 : GOTY edition is an evil game that is about rolling a dice and getting a high score. The game contains multiple easter eggs and will save your progress so you can always come back and enjoy your game.
    (progress is saved when the ending line is on screen)

    This game was made by me and all the nice people that helped me out on #cobalt


  19. TP :

    Here we go I got up early and here`s the result of ~4h of Coding Fun:

    Kitty Clickiller
    You wanted an evil game you got yourself an evil game. Click to feel like a monster. Click more to feel even worse. Right click to hire minions to do the dirty work for you.

    Made by me (TP) using the löve2d lua engine

    For Windows just download the Executable extract and run it. For Mac OS, Linux etc. download the .love and check the Löve2D homepage for more information on how to run it on your system.

    My jam entry!

    Name of the game: NyahaBOOM!
    Link to game: https://dl.dropboxusercontent.com/u/8203408/ohgodwhy.zip
    Special instructions if needed: This game is broke to hell. Read the readme.
    Description: Catshooting cat tanks of the Catocalypse! Or atleast it was supposed to be that way…
    Author: RayKatz
    Link to screenshot: http://i.imgur.com/QXNnNBB.png

    Next time I will complete whatever I started!

  21. RayKatz :

    What I learned over the duration of the jam:
    - use version control
    - don’t learn and use a new plugin while developing under time pressure

  22. Rian :

    My submission is “Goolord Rex: Destroyer, Annihilator, Cat?”. I only had a couple of hours to make it so it’s unfinished at best, and there are no sounds. It’s written in Scala (so it runs on the JVM and should work on mac, linux and windows) as functional and pure as I can handle. The graphics are done with Swing. The game is a shooter with a twist. You catch enemies with slimeballs and collect them to get points. The more points you have the more difficult it gets. You have a limited amount of ammo, but you can retrieve every slimeball, so don’t let them fall. I think the theme Evil is currently only present in its difficulty, but the themes Cat, Slime, Arcade, Shooter and Fast are definitely included.

    Game name CatDefence
    Author Peter Goode (mrexcessive)
    Link to game http://web2.mrexcessive.net/CatDefence
    HTML5 game, so should work on most things.

    So… only discovered your compo yesterday evening… Spent about 6 hours I think total. Construct2 great for prototyping.

    Hopefully while provide 90 seconds of fun!

  25. Janeator :

    Had a really good time during the game jam!

    It’s been a long time since I had done anything artistic (other than mapping :D ) and I feel proud of the results, really enjoyed the time I spent making it.
    Thanks again to JanSedivy for pulling me into teaming up with him, and for all the code he’s done!
    Also thanks to NameIsNotName for the track :)

    Hopefully we will soon release a “full” version of the game!

    - by DolanCZ “the most not programing guy on Cobalt IRC”.

    You can download the game here : https://docs.google.com/file/d/0B1VtYjQkgYKiWWNaLWtXbkl3TVk/edit
    (There is a bonus file there too)

    It’s a basic console game I created just for fun, since I am not able to do advanced stuff, just because I don’t know how. I am really noob in this, but since any game counts, I joined this community event!

    When you discover the main theme of this game, it’s really easy to finish it. Plus it is kinda only for people that know Oxeye with some inside stuff around this community.

    You can finish this game in less than 2 minutes if you are fast.

    “This game is just some fool’y things put together in 2 days” – Have fun!

    * Sneaks under the rug like a paper ninja *
    Evil Sheep Game – by Samuel “MrOverkill” Meyers

    I was a little over-ambitious with this one, but i’ll apply fixes to it and make it work better as time goes by.

    This is a game where you gather crap from the good sheep and throw it at the evil sheep so they don’t turn your good sheep evil.

    The game is written in Java, with python scripting making up the gameplay. It’s also public domain, so modify it all you like. :)

    Updates page ( Where binary builds will be posted ) : http://www.epicknife.com/games/evilsheep/

  28. Samuel "MrOverkill" Meyers :

    Also, i’d like to note that there are several things i’ve learned from this game jam.
    1. NEVER EVER EVER make AI for a game jam.
    2. Know what you want to do before you start.
    3. Eat more food when coding.

    “Bricks” – by Ivan Becker Druckman

    No highscores system yet, D:. You’re a brick throwing robot, the main objective is to kill as many people as you can with bricks. Try to get a bunch of points!

    Please take my submission! I thought the jam ended at 12 am, not pm…

  30. Ivan :

    Also, during short game jams:
    2. Don’t get sick…
    3. Always make sure you get the end time correct.

  31. Isogash :

    “Super Insane Robot Demolition TV” – By Isogash

    It’s a TV show about destroying innocent robots with vast arrays of missiles. You are that robot, good luck! Can you beat your peers in the missile dodgey game of the century?

  33. Librus :

    I’m still working on it, guys! I’ll show it off when I’m done, and I believe it may take a while to reach that status…

  34. Pedro Alves :

    I wish I found this earlier. I made a game that would be cool for Game Jam (I made it when I saw this). Its very evil, but I’m not going to share it because it’s not complete.

  35. Link :

    Wow DolanCZ your game is way to evil. xD

  36. Kenny Weston :

    I will try my best

  37. Hienzo :
