ColorFiller 3DS

ColorFiller is an open source homebrew recreation of FlowFree in C++ for the 3DS.

Installation

Available in 3DSX format.

Connect the 2 points with the same color, and fill the board to win.

More levels can be added by dumping the levelpack_*.txt from the assets folder of the game APK. To do so:

Use an apk dumper application on your phone to get the file, then open it with 7-zip or your favourite archive extractor.
Put the level packs you want in a levels folder in the same directory as the convert_level_packs.py file, then run said file (requires Python 3.6+).
Copy the output file levels.zip to your 3DS' SD card, at the path specified by the levels_path settings of your configuration file (the default is sd:/3ds/ColorFillerLevels.zip).
You are now ready to play the game.

Note: Changing your levels file can invalidate your save file, so it is recommended to make backups.

Big Duck Games for the original game, check them out and buy the extra packs. They deserve it, and playing on phone is a much better experience.
