Writing a HTML5 game in Python (almost)

Posted by
Saturday, December 12th, 2015 9:18 pm

Trying to participate again…

This time my goal, besides finishing a game, is to become familiar with Rapydscript .

Rapydscript is a subset of Python that transpiles to Javascript.

So I’m writing a HTML5 game in Python (almost) using Phaser. I’m creating a simple wrapper of Phaser for Rapydscript (Physer), so my game code passes the PEP8 and other Python tests…

This is how the game code looks like so far:


As you can see, besides the camel case in some methods (Phaser standard) it looks and feels like Python.

And this is how it looks so far:


You can try v0.001 here.


Good luck to all

Simple platform gameplay… a scientific in a jetpac.

Connected worlds!!! So I’m in.

This is going to be my 13th game for Ludum dare (8 for the main contest and 4 for mini-LDs). You can check my previous one here.

My desk this time… with the baby monitor over the main desk.



I would probably make some kind of platformer using:


  • Language: AS3
  • Library: Starling + StarlingPunk
  • IDE: Flash Builder


  • Paint.net

Music and sounds:

  • SFXR
  • Chordpulse


Good luck to all!!

Demaking Manic Miner

Posted by
Saturday, March 22nd, 2014 10:29 pm

Manic Miner is one of the earliest platform games.. and probably the first one I played. It was made for the ZX Spectrum in 1983 by Matthew Smith . More info in here.

I’m demaking this mega classic game, as It would have been made in 1981 instead of 1983 using a IBM PC with CGA graphics card (I didnt know this card until the 90’s IIRC). More info here.

I’m using Construct 2, and so far I have first two screens… platform physics is different but good enough to homage this great game…

This is the original…

This is mine…

You can try it here. (cursor to move, Z to jump).

My plan is to add tomorrow:

  • Intro screen
  • Level 3
  • Sfx and bgm

Forgot about my own game :(

After rating 30+ games I found a couple of them interpreted the theme like you have one bullet/arrow/bomb that you throw to kill enemies and you have to pick up to use again…

and I honestly believe that it is a better interpretation than mine (one minute to complete the level)…

everything OK so far, until I remembered that I made a game like this three years ago.. and that I forgot about it when thinking about the theme.

This is the game: The Mayan Ball

This is my entry if you want to compare:

Best luck to all!!!


Submitting “1 Minute Capsule”

Posted by
Sunday, December 15th, 2013 5:35 pm

A new game!!!
Entry is here

In 1 Minute capsule use the left and right arrow keys to rotate the playfield and the gravity to guide your capsule to the checkered flag. Green blocks start to appear when you are close to the flag.

You have just one minute to complete each state.

Press image to go the entry

HTML5 version requires WebGL and it has graphics glitches.

I recommend the Windows version.

All content was made by me using:

  • Game Maker Studio
  • Paint.net
  • ChordPulse
  • Mixcraft 5
  • SFXR



1 Minute Capsule “playable version”

Posted by
Saturday, December 14th, 2013 5:36 pm

It’s been one night and one day full of work…. I managed to get a “playable” version of my idea.

1 Minute capsule is a simple game: the player has to rotate the screen and the gravity using the arrow keys. You have to guide your capsule thtough the maze avoiding black holes and trying to get to the chequered flag in one minute.

It’s been made using Game Maker Studio (I will probably move onto actionscript if I can) and I have exported it to HTML5 (it requires a WebGL enabled browser)

To do:

  • Sounds
  • BG Music
  • More enemies
  • More block types
  • Better gfxs



Good luck to all…. best regards from Chile!!!

Not enough time…

Posted by
Sunday, August 25th, 2013 10:05 pm

No time during this weekend.. real life,

I only had 6-8 hours I spent working with Away3D and Flash Builder. My plan was to make a FPS-like game… I may work tomorrow a little and submit a Jam “game”… If I receive enough hearts in this post 😉 .

This is what I have so far: simple FPS camera ( a la Wolfenstein 3D), blocks and slide-collision,

“Engine” test

Click image to play, move with arrows (shift  to strafe).

Two hours to setup FB + Away3d

I just spent two hours to setup Flash Builder + away3d :(


I almost haven’t thought about the theme, yet.

I shouldn’t be doing this!!!

Yes.. I have so many pending things to do in real life… but anyway…

This is a very simple game: you are the blue army, your enemy is the red one, neutral cities are white.

Select your city and any other one to send part of  your army.

This is the first early-alpha-don’t-show-it version

End of the day for “A day in the life of The Minotaur”

Posted by

The Minotaur is a little tired…

The game design is almost complete: You are the Minotaur and every day is the same, the nice people of Crete send you a virgin to sacrifice and warriors show up to defeat you… mmmm… warrriors.


“A day in the life of The Minotaur” is a board game (yes like the ones with dices) x Roguelike. The board generation is procedural and you move throwing he dices. If you face a bifurcation you have to decide which way to follow. A cell of the board can have an item or an enemy. You win when you find the virgin and sacrifice her…


  • Board random generation
  • First version of gfx
  • Board scrolling
  • Simple HUD
  • Dice throwing
  • Minotaur movement
  • Goal and new level


Left to do:

  • Enemies, treasures and energy (are already there but they do nothing) so if you land in a cell with gold, for instance, you should get gold coins 😛
  • I may implement a combat mini game
  • Much better HUD
  • Sound effects
  • Epic Music
  • Dice animation
  • Cut scenes or at lest lines.

You can try it here: v0.3

See you tomorrow!!!

… you live in a laberynth… all days are similar… they bring you a virgin to sacrifice and a couple of heros show up to try to kill you.

Made a game in 48hrs.. but after compo deadline :(

Posted by
Sunday, August 26th, 2012 10:36 pm


I did make a game in less than 48 hours, unfortunately I couldn’t submit it because I run out of time.

I wasted friday night and saturday working in a gameplay that didn’t work very well and it wasn’t funny at all.

On sunday I had only 5 to 6 hours to put together a new game mechanic, and finished a couple of hours after deadline.

Anyway, I submitted the game to the Jam compo (entry here)… and maybe tomorrow (I still have like 20 hrs) I made some changes to parts of the game that need improvements: more levels, better music and I may invite some friends to improve the graphics.

This is my 48 hrs game in case you care: 48 hrs HTML5 version

Good luck to all!!!

MiniLD #34 – Still working (64×18 resolution)

Posted by
Sunday, May 20th, 2012 7:15 pm

Hi all,

I’m still working on my (nameless) entry :) It’s a 64×18 shooter. Due to a family reunion I haven’t had more than 8 hrs.

You can try it:
Mac OS-X (untested)
Linux (untested)

As it’s almost impossible to play at the native resolution press the following keys to get a zoom level:
1 -> no zoom (64×18)
2 -> 2x zoom
3 -> 4x zoom
4 -> 8x zoom (default)
5 -> 16x zoom

Move using arrows

I’m using: GLBasic, Paint.net, ChordPulse, Audacity, GXSCC, SFXR.

I’m planning to release an Android version.

Best regards
