Danceball community · Created a new topic Welcome!

I'm interested to hear your thoughts.

Re-use disclosure: used some graphics and sound from my previous games, as well as some snippets of code.

this is a work in progress. hope you enjoy. i'll keep updating it until the end of the jam :)

Welcome to the jam! looking forward to the results. Swing by #lispgames on freenode IRC if you can :)

i like Simplescreenrecorder for linux. it can do 720p 60fps. If you record to webm you can then use to get a nice gif.

very nice! the sky gradient and especially the little drop shadow

hi i am looking forward to seeing what you come up with :)

are you thinking about procedural generation of terrain features?

I've been testing out Shinmera's Portacle :

It is an easy to install, integrated GNU Emacs / Common Lisp / Quicklisp / Git tools for Windows, Mac, and Linux.

Any required libraries (DLLs on windows) can go in the ./portacle/lib folder, and your added lisp code goes in ./portacle/projects

If you try it out please let us know about your experience!

Works great on a Win10 laptop here.

Hello! I'll be making some sort of GUI game where you have to defeat windows and buttons and resize your enemies and such, or shoot letters at them. It's to demo my newly-ported GUI code and make something fun with it.

this looks awesome. do you know if it will work under the Wine system in Linux? Many windows EXE's do.

If you like 3x0ng please make a post saying Hello! Say a little something about yourself and what games you like.

Please report any bugs here. I will respond with fixes whenever and wherever possible.

When reporting, please let me know:

  • Which platform you are running on (Win/Mac/Linux)
  • Which version of the game you are using
  • Preferably a screenshot of bad behavior and/or any error messages

Hello to the community! I have opened a community message board here for 3x0ng, my retro versus soccer-breakout-pong game. You can see a recent vid here of my friend and I playing a local versus match with gamepads: 3x0ng Smack Talk on YouTube

I would love to hear your comments and will be happy to answer any questions, accept bug reports, and receive feedback. I can also consider and possibly implement your feature/fix ideas!

I am also looking for people to test the network gameplay! It works but hasn't been extensively tested. I would love it if some people tried to play with each other, or even with me! It'll help if you can forward one port to your machine... a basic UPnP client is included, but it doesn't work with some routers at the moment---so the player running the Server instance will need a port open.

So that's my pitch----join the 3x0ng forums, download the game and try it for yourself! I really like the direction development is going in---it's become one of my personal favorite projects. Accordingly I'd like to implement more gameplay modes and options, further improve the AI for single-player mode, implement player suggestions, and refine the netplay experience.

You can participate! 3x0ng is available FREE for Windows, Mac OSX, and Linux and is Free Software under LGPL. Grab your gamepad (or the arrow keys!) and have fun! And please enjoy the forum---I want to hear your comments and suggestions.

Thanks! ----David O'Toole

Hi Fidgety thank you for playing, and thanks for your kind words. I agree that more work is needed in some areas, and I would definitely like to step up my game designs to the next level. I am moving into the world of 3-D for my next game, a reboot of 2x0ng for later in 2017. I hope my next releases address the issues you raised. Thanks again for taking the time to play (and comment!) and I hope you will check out my future games.

I used to love Time Pilot on the Colecovision :)

Awesome post!!!

Let me know via IRC (dto on #lispgames) or email

hi, i can give you a late submission URL if you message me on IRC

I'm so happy to see everyone participating and posting :)

I thought I'd also mention for those who may have missed the news, we are having the New England Lisp Games Conference here in Massachusetts, USA on August 13th: it is a free event at a cool video arcade with hands-on demos, tech talks about lisp games, and a big-screen 3x0ng mini-tournament. :) and I hope to see you there!

cool i will check it out! also i enjoyed reading your article. there is a lot of valuable information on getting things done in a jam :) I'm happy to see people using the messageboard, it is a nice feature of doing the jams here at itch.

Version 2.2 is up with additional graphics effects, a new enemy, and more.

Made a nice new trailer :)

Version 1.8 now adds Multiplayer! Local co-op and client/server network co-op are supported. The network features of my engine are still in beta, so network play might experience problems. Please let me know if you experience issues with the game and email me at or drop a note here.

Version 1.7 is up on Windows, Mac, and Linux.

  • Now includes ambient music (toggle with Control-M)
  • Interpolate bullet positions to prevent missed collisions
  • Final boss now fires robots! Which then fire lasers at you
  • Tweak oxygen timer and other difficulty curves

So, what's next? Possible future developments:

  • More levels and bosses
  • Improve graphics
  • Co-op and versus modes with my engine's network play

Version 1.4 is now up! I've improved the phosphor effect and spiffed up the website a bit.

a somewhat more janky shader

Version 1.2 now has pseudo CRT shader fx!

I've released v1.0 with final boss, victory screen, more adjustments, and a new Drone enemy who chases you around.

A nice new video of the new release:

Updated to 0.9 with several bug fixes. This is so much fun!

I'm also happy to announce that the game is now available on Mac OSX as well.

Updated to 0.8 with plenty of improvements:

  • Improved terrain generation
  • Award extra life at every 5 levels
  • Changed player-bouncy-bullet color to avoid confusion with enemy bouncy bullets.
  • Call garbage collector during each level transition
  • Fix collision detection issue with player bullet in some cases with stationary enemies

this gives me the Compile shmup feels

love it (zanac, gunhed, guardian legend and more...)

Updated to version 0.7 today with the following new changes:

  • Find oxygen tanks to relieve time pressure
  • Three kinds of powerups: Bouncy Bullets, Invincibility, and Rapid Fire.
  • Improvements to difficulty curve and lighting
  • Hit Control-P to pause/resume gameplay.

woohoo! i love it

Just added v0.6 with changes to the difficulty curve, debugged mismunch enemy, and most importantly DARKNESS! After a certain point you will sometimes experience dark levels with limited visibility.

Just added version 0.5 with improved heads-up display, another new enemy, oxygen and other difficulty tweaks. You now have three lives with which to retry. Darkness is not yet implemented. Gonna keep working on it.

Plans for next version 0.5:

  • Limited visibility on darkness levels
  • Find oxygen tanks sometimes
  • More enemies
  • Improve terrain and possibly allow larger levels

I am working on a good old fashioned robot shooting game for our 2016 Spring Lisp Game Jam: now available in playable alpha on Windows and Linux. (Mac version soon.)

The game is called INV8R:

The newest release (v0.4) includes level generation improvements, a new enemy that shoots bouncing blue lasers, and an Oxygen gauge that will kill you if you don't complete the level in time. This is accompanied by color coding and sound effects. Here is a video:

And another nice animated GIF:

I will be updating this Itch devlog with each new release, and would love to hear any feedback you might have. I have 7 days remaining in the game jam, and I'll be putting out 0.5, 0.6, 0.7 until finally 1.0 is submitted for the jam deadline. I'd like to continue developing the game after that time and expand it a bit further.

I'll be hacking some more today on the game and I'll post some other thoughts as well.

I hope you find the Gifs interesting and consider playing the game!
