Viewing post in Shape Beats Tech Demo comments
I tend to keep things simple if they don't need the added complexity. Especially since I'm trying to take a novel approach to doing a rhythm game, and I can't have complex graphics getting in the way of performance.
Plus, this is just a technical demo meant to be a supplement for someone looking at the code without the option of building the game (ie in the github repo).
