The menu seems to flash on my screen before terminating:

Checking '/dev/input/js0'
Failed to init libevdev (Invalid argument)
Checking '/dev/input/event15'
Checking '/dev/input/event14'
Failed to init libevdev (Bad file descriptor)

so 2 small problems:

1: linevdev seems to need root permission to grab my keyboard

2: you grab the the first keyboard, so if  you have a steam controller and a keyboard, you can't use both.

Otherwise, it's nice to have a playable game that rely on so few libraries.
