Looking at how the device was marketed as being easy to develop for, I was assuming it would be the physical equivalent of something like the pico-8.
Pico-8 is known for it's openness to hackability, and users have implemented features that aren't originally provided by the API like sprite dithering and 3D rendering.
But looks like the device has really under-powered hardware to provide that, especially given the price.
If the playdate SDK doesn't allow poking around into raw memory, it's wasted potential in my opinion.
