Switcher – Post Mortem

Posted by (twitter: @ehtd)
Thursday, May 1st, 2014 8:25 am


Switcher is an endless running game with a twist. You are the enemy, it is not because you are the bad protagonist, it is because the protagonist is different. The world fears different. Your choices are to run/fight or die.

The bad

The 48 hours compo is extremely exhausting, at least for me. I can not sacrifice sleep hours since at the end of the compo I still have to go to my 8-5 day job. Instead of using the 48 hours I ended up using maybe just about 20.

I tried also a new engine Phaser to deliver a web game. It went smooth most of the time, except by the one time I hit a bug and waste 2 hours. If I had practiced more, those two lost hours could be used in polishing the game.

The last show stopper was when I was about to deploy the final version. Compressed my zip and upload to just to have it fail with an error of zip containing more than 500 files! I had only about 20 files and didn’t understood what happened. In the end it was a dummy error. I was using git as version control and I was zipping all the git files as well. About another wasted hour.

The good

Phaser was definitely a good choice. It allowed me to deploy fast and deliver to most of web viewers the game. Accessibility is king. For voting since I have a Mac, I can not vote on Windows games and also have some trouble with Java games. I however had no trouble running flash/hmtl/unity web games.

Designing on pixel art was also good, I have been doing pixel art for almost 2 years now and I am happy I have reached the point to finally release acceptable pixel art, at least pixel art that players can enjoy.

Version control was definitely a great asset. Other games I have delivered for LD were on game maker, which greatly difficult the versioning. This time I was working on pure code and versioning is a bliss.

Improvement Areas

  • Music is missing from the game. For the next game I will try to make time for this.
  • Polishing was also a missing point. I did some polishing but not as much as I wanted. I think the game should be ready, not just feature complete, by the first 24 hours. At least the code and art. Then try to get some feedback with friends, family, or someone and adjust and polish the game the next 24 hours. A really cool game can be killed if it is not polished enough.


Language/Engine: JavaScript/Phaser

Version control: Git

Text Editor: Sublime 2

Pixeling: Pixen

Debugging web browser: Firefox

My third Ludum Dare!

This will be my third ludum dare and I am exited! Participating is always tiring at the end, but the results are always awesome. For my last two participations I did my games with game maker, which is a really cool engine, but the problem for me was the accessibility on windows desktop. I have learned now a feature to export to mac and html5, but the html5 didn’t worked as good as I hoped.

This time I am making an accessibility first approach, complete code designed to run in browsers. My tools:

  • Language: Javascript/HTML5
  • Editor: Sublime? TextMate?
  • Libraries: Phaser
  • Art:
  • Sound: SFXR

I have just tried Phaser and it looks really good.

Have fun and make great games.

Post Mortem – Monster Interceptor – Making a game in 15 steps

Posted by (twitter: @ehtd)
Tuesday, December 31st, 2013 5:03 pm

I am the creator of Monster Interceptor. A game on which you control a pulsar gun, with the objective of reaching and stopping an alien invasion.





Development process

This time I wanted to reach a larger audience and tried to develop using Lōve instead of game maker. But as the time passed I decided to get back to game maker and reach my objective: Finish the game. Next are the steps I did:

1. Get the theme – You only get one

2. Brainstorming for ideas

3. Sketch basic functionality of selected idea

4. Install lōve and run some tests.

5. Implement the pulsar ray. (took a long time… 4-5 hours)

6. Rant about my slow progress using lua.

7. Switch to game maker!

8. Implement again the pulsar ray (Just 30 minutes in game maker)

9. Tweak the pulsar ray for smoothness.

10. Add space exploration room

11. Add menus

12. Add pulsar ray eye candy (paint the trajectory of the “bullet”)

13. Time to add sound effects! (And failed… skip sound effects!)

14. Time to add music! success!

15. Submit


What went right

– I had previously joined LD48 and knew about the time constrains and knew the submit process so there were no surprises there.

– This time I tried to do a very simple idea and incrementally polish until the time was up.

– Experience as a software developer allowed me to make better decisions. (Inheritance, design patterns, etc…)


What went wrong

– Starting with lōve and lua with no experience on them. Definitely a really bad decision.

– Weird bug on sound effects.


The result

Here is my game, I hope you enjoy playing it as much much as I did developing!
