So, my first Ludum Dare was a success. My first objective for this edition was to manage to finish something, and at the end I had plenty of time to deliver so, probably, I was too cautious with my estimation.

What went right?

  • Programming language and libraries: I have relied, mainly on plain C++ and simple SDL which proved to work quite well to program a simple game.
  • Data driven: Making the levels data driven was a VERY lucky choice. I was able to tweak them quite easily, although for the next jam I’m going with a tool
  • Sound Effects: sfxr worked awesome. And FX really add a lot to the project.
  • Pixel art: Maybe I see the game through fathers eyes, but I think the simplistic 8-bit look makes programmer art looks pretty decent.
  • Planning: Since I decided to participate, I had a timetable in mind. I’ve managed to be “on time” for the full weekend. Saturday night I had the game with graphics, music, sfx and I made a “beta” version which tested on my father computer (if you work on Windows you MUST do this). I was able to expend sunday morning polishing the levels and music. Even I had time to add a new type of enemy in the game.

What went wrong?

  • Lack of art skills: I’m pretty comfortable programming but I’ve found I lack art skills. Not only unfamiliarity with tools, although PyxelEdit had some quirks (like not remembering last used folders) and lacks some way of previewing animations (or I didn’t know how to do it), I had never animated a sprite and couldn’t get a walk animation I liked. I even decided to switch to a simplistic character, because it was easier to animate.
  • Lack of a tool: Making the game data driven was a good choice, but for next compo I think I need to experiment with some tool to layout the sprites. If you check my Timelapse you’ll see I expend a lot of time tweaking the numbers in a text file. Manipulating text files with Vim is quite easy, but being my first time making art I didn’t prepare the sprites in a way they were easing to remember (nor made a reference chart, although I had one for enemies).
  • Theme: I wanted to do something original and, while I think my idea of going for a Borrowers theme was nifty, I don’t think I was able to put that on the game.
  • More mechanics: I wanted to keep the game short, but the biggest improvement I left out  was adding a new set of enemies and levels based on “ice” (the food section). I think I have almost exploited fully the tools I had for designing levels. The game is quite easy as it is now, but I have tried to don’t require the player to use double jump or the wall jump.
  • Testing: I only had 2 other computers at home without development environment, so my test cases weren’t able to cover the full range of problems people have been finding in the game. I should have added more error checking code and a MessageBox, so I can find why people can’t run the game. Next time, I will do a very simple warmup game with the boilerplate I’ll use and try to test it in as many machines I can find.


I had a lot of fun programming Arnold Bros and I plan to refactor the code and try improving the graphics as a way to get some pixel art skill for the next Ludum Dare. If I can I’ll try to get friday and monday off work so I can squeeze some extra hours to add ambition to the project and to do some preparation before the jam.
