Hey Phillip, thanks for hosting this jam, super excited about it.
I know it's not going to affect jam scores - I'm more interested from a technical perspective, but where does the limit of 15 fps come from?
I have one of the PCD8544 screens at home, and I can update it at much faster rates - I'd say even 120Hz appears to be possible correction: the datasheet states a typical frame frequency of 67Hz. I've also seen a few videos like this one where the games look much smoother than 15fps. I'm currently considering whether I write the jam game so it can both run on the PCD8544 screen and in a browser because I think that would be really sweet, but I just want to get these details right.
Thanks =)
