The game that will run on my cabinet is coming along nicely. The game is based on Super Crate Box, and follows the original closely. Four weapons are implemented right now (pistols, dual pistols, machine gun, grenade launcher), as well as 2 enemies and 2 levels. Here is some footage of the game that will be running, recorded on my laptop.
Sadly, YouTube screwed up the framerate , as it runs fine on my MacBook and even on my pi. The game will eventually include another enemy, 3 levels and 10 weapons. Besides that, highscores have to be implemented, and the APA102 LED strip needs to be integrated into the system.
