For those interested, I added a real Linux build, not just raspberry PI. Also added OS X.
Retro Island War
A downloadable game for Windows, macOS, and Linux
My Linux Game Jam 2017 entry.
Mainly built for the raspberry pi model 2 B with an XArcade keyboard attached. Normal keyboard scheme can be picked at launch.
In my particular case, the PI is integrated inside the XArcade keyboard making it a complete machine by itself that can be plugged to a monitor. I use remote connect with Putty to debug/launch the game on it.
OS X WARNING: Execute ./RetroIslandWar_OSX from terminal on Mac. (I know why, didn't find the time to fix it yet)
Please report any problems.
