My participation in the Compo over time
For my latest two entries I use 8 colored (3-bit) images. They are stored as text strings, encoded in a way not using special ASCII characters. This makes the data suitable for archiving. The method for storing was invented by one of the jam participants - @xem. I extended his miniPixelArt tool and made it possible to load image files:
Note: Flash Player plugin and Pop-up functionality must be allowed before using the tool
In Super Bunny Strikes Back I have two playable main characters and they comprise significant portion of the sprites used in the game. I knew there won't be much space and decided not to cut from their 6-frame jumping animations, but rather reduce the enemy creatures count and diverse them with different color pallets (changing colors is quite trivial if you use the Image Encryptor).
The sprites I used have 7 colors and transparency. In addition I use a special approach to mimic a contour by applying a drop shadow filter on all images. This comes with a bit of limitation on what can be drawn with the sprites - for example you can't place two pixels of contour vertically next to each other. But with a little effort this can be walked around with suitable pixel art.
To be continued...
